Welcome to the second issue of our Quarterly magazine. Since I wrote the foreword to my first ‚Quarterly‘ a few 

weeks ago, the unimaginable has happened: we have war in Europe again. Following the pictures and reports from 

Ukraine makes us all concerned and sad. In addition to the economic consequences we have drawn since the beginning 

of the war, we as a company are trying to support aid organisations and offer refugees from Ukraine a professional 

perspective. We all hope that this terrible war will end soon. 

In my first few weeks at Bürklin Elektronik I have had many interesting discussions with customers and suppliers 

and also received a great response to the first 2022 issue of the magazine three months ago (14.02.2022). I would 

like to thank you very much for this. 

We at Bürklin Elektronik are working flat out to continuously develop both the customer and supplier experience. 

A competent range of products from renowned and innovative manufacturers, available the same day from our 

warehouse in Munich is the core of our performance promise to our customers in Germany, Europe and worldwide. 

In the next few months we will go live with our new online shop - another important milestone in the long successful 

history of Bürklin Elektronik. Caren (head of our e-commerce team) already offers a small foretaste of our 

new shop in this issue. The new online shop will complete our transformation from the first and leading catalogue 

distributor in Germany to a European/international digital distributor based in Munich. 

In addition to the article about our new online shop, we have compiled numerous interesting topics for you. 

You can also find current information about our company and vacancies on Linkedin. 

Visit us - it‘s worth it. 

Enjoy reading and stay healthy.

OPTIMIZED SEARCH 

SMART BÜRKLIN 

ONLINE SHOP 

THE NEW SEARCH AS A CENTRAL ELEMENT 

OF THE NEW ONLINE SHOP IMPROVES THE FINDABILITY AND 

PRESENTATION OF THE ENTIRE RANGE OF OUR PRODUCTS. 

TECHNOLOGY CHANGE 

& GO-LIVE REALIZATION 

As reported in Quarterly 

#01/2022, Bürklin 

Elektronik has decided to 

change the technology in 

the current project and as 

a result to realign the project. 

Our implementation 

partner Bits&Minds GmbH 

will develop a storefront for 

us based on our individual 

Bürklin requirements - 

the shop window into our 

range of electronics products. 

Together we plan 

to realize an anticipated 

Go-Live of the new online 

shop in the first half of 

2022. 

INSIGHTS INTO 

THE OPTIMIZED 

BÜRKLIN SEARCH 

On the following pages 

we would like to introduce 

you - dear customers and 

suppliers - to the heart of 

our new online shop in detail 

- our optimized Bürklin 

search. This new search 

enables our customers to 

find the perfect non-trivial 

orientation in our assortment 

of products – around 

500,000 products from over 

5000 well-known manufacturers. 

We would like 

to show you how you can 

quickly and easily find your 

desired products with just 

a few clicks, what the advantages 

of the new search 

are and much more. 

ACCURATE SEARCH 

RESULTS IN THE 

ONLINE SHOP 

What used to take place 

in the Bürklin store in a 

dialog between customer 

and sales staff is now 

in the digital age often 

reduced to customer´s 

just entering a few search 

terms in the online shop 

and getting matching articles 

displayed. The focus 

is thus on a high-quality 

search that enables customers 

to make their own 

product selection in the 

online shop. 

BASIS: 

HIGH DATA QUALITY 

The basis for a good 

search is relevant and 

high-quality product data. 

One of the key jobs of the 

content team is to furnish 

articles sold in the online 

ship with descriptive attributes 

so that the articles 

can be found more easily. 

We already reported in 

detail on product data 

management, its challenges 

and our PIM system 

Contene in Quarterly 

#03/2021.

TECHNICAL 

IMPLEMENTATION & 

CONTINUOUS 

IMPROVEMENT 

Bürklin Elektronik uses 

Elasticsearch as the basis 

for its search. The fact that 

Bits&Minds GmbH is also 

an official Elastic partner 

means an enormously 

important advantage for 

Bürklin Elektronik, also in 

the future: store development 

and continuous 

optimization of the search 

from a single source! 

All our requirements & 

customer needs can be 

implemented individually 

and flexible. The programming 

of the search and its 

functions is a continuous 

development process, 

which is based on facts 

and figures of our customers‘ 

search behavior 

and continuously considers 

customer feedback on the 

current online shop. 

COOPERATION 

BÜRKLIN ELEKTRONIK + 

BITS&MINDS GmbH 

Bits&Minds GmbH has 

been successfully active in 

individual software development 

for many years. 

Due to the large wealth of 

experience and the high 

professional competence, 

even particularly demanding 

projects can be successfully 

implemented. 

In addition, applications 

with extensive and complex 

searches on large 

amounts of data represents 

a main competence 

of Bits&Minds GmbH. The 

technical implementation 

is always complemented 

with competent advice and 

support from the specialist 

department. This makes 

it possible to optimally set 

up and successfully integrate 

a search. 

OUR PROMISE TO YOU: 

OPTIMIZED SEARCH 

Our customers will find the 

products they are looking 

for easily and quickly with 

the help of the comprehensive 

search and filter 

functions. 

REAL-TIME PRICES 

& AVAILABILITY 

Prices & availability are 

displayed in real time – 

based on the data in our 

merchandise management 

system. 

INTUITIVE USABILITY 

& ORIENTATION 

The user-friendly design 

with a very good usability, 

an intuitive orientation and 

a fast-loading time will 

enthuse our customers. 

EXTENDED CUSTOMER 

SELF-SERVICE 

FUNCTIONS 

With extended customer 

self-services we create 

a clear added value and 

optimize the purchasing 

processes of our professional 

customers in the 

long term. 

PORTFOLIO DESIGN 

& DATA QUALITY 

We communicate to our 

customers the entire 

range of our electronics 

products in the new online 

shop in a user-friendly 

and comprehensible way. 

SIMPLY & QUICKLY 

TO THE RIGHT RESULT 

Since the discontinuation 

of the famous Bürklin catalog 

it is a constant challenge 

for us to represent 

this wealth of different 

products with all their various 

technical features in 

an online shop. Since the 

beginning of the project, 

we have put a special focus 

on the new search: THE 

ENTIRE RANGE OF OUR 

ELECTRONICS PRODUCTS 

should be comprehensible. 

We want to make it as easy 

as possible for our users 

- you, dear customers - to 

find what you are looking 

for. It should be a pleasure 

to click through the 

assortment and to find the 

matching accessories or 

the substitution article in 

addition to the article you 

are looking for. Searches 

within the online shop 

should quickly lead to a 

suitable result and further 

narrowing down should be 

effortless. 

WANTED? - FOUND! 

Basically, we can distinguish 

the two common 

types of user behavior in 

our online shop. 

1. someone is looking for 

a component or an article 

for a specific purpose. The 

requirements are clear, 

but there is some flexibility 

e.g. in the choice of manufacturer 

or form factor. 

2. For a very specific 

component is searched. 

Maybe even already with 

the corresponding known 

Bürklin number often also 

based on the manufacturer 

part number. 

We will accommodate both 

variants equally in our new 

online shop. 

ACCESS VIA 

OUR PRODUCT MENU 

If you are looking for a 

capacitor you have for 

example the possibility to 

select the corresponding 

category via our usual 

product menu or to enter 

via the appropriate subcategory, 

e.g. Wired Resistors. 

NEW PRODUCT FILTER 

ON ALL 

SEARCH RESULTS PAGES 

So far, so well known. But 

already in the 1st sublevel 

comes the first innovation! 

There you will find our new 

product filter. Here we 

have paid special attention 

to make it as easy and 

fast as possible for you to 

filter out the desired item 

from the product set based 

on different but always 

matching properties. 

The filters include some 

basic filters, which are the 

same in every category or 

on every search results 

page. For example, the 

manufacturer selection 

or filtering for in-stock 

products. 



9

DYNAMICALLY 

BUILT FILTERS 

MULTIPLE SELECTION 

PER FILTER 

Below you will find the 

dynamically built filters 

for the technical characteristics 

of the products 

you are looking for. In the 

category „leaded resistors“ 

the ohmic resistance, the 

power and tolerance are 

immediately found as important 

filter criteria - but 

beyond that supplemented 

with further dynamically 

calculated filters. 

SEARCH FOR VALUES 

& ADJUST UNITS 

Within the filters you can 

search for values and in 

case of numeric values 

adjust the unit. 

For example, if I am looking 

for a wired resistor with 

10kOhm, I can quickly and 

easily set the unit to kOhm 

and filter for „10“, or I leave 

the unit at Ohm and search 

for „10000“. Both leads to 

success. 

THE FILTERS ARE 

REGENERATED 

IMMEDIATELY AFTER 

EACH FILTERING 

In parallel and immediately 

the dynamic filters are 

regenerated. All filter 

values available for selection 

come from articles 

that match the previously 

selected criteria. You will 

not be confronted with impossible 

filter combinations 

or unavailable filter values. 

With only a few clicks you 

can quickly and comfortably 

set all necessary criteria 

via the filters. Try it out and 

browse through the depths 

of our assortment and 

discover new products or 

similar products of higher 

quality or at a lower price! 

It is also possible to set 

multiple values per filter, 

e.g. you can search resistors 

with a certain ohmic 

value, but limit the tolerance 

only a little. 

In the view result list you 

can compare the products 

at a glance. Analogous to 

the filters the properties 

arranged in columns are 

displayed optimally. 

COMPARE TECHNICAL 

PROPERTIES AT A 

GLANCE 

The technical properties 

are displayed directly on 

the right. This way you 

always keep an overview 

and can sort again in your 

already pre-filtered list 

by clicking on the column 

header. 

If you want an explicit and 

detailed product comparison 

between several 

products, you can also use 

our new product comparison 

for this purpose. 

DISPLAY OF 

PRODUCT VARIANTS 

In the new online shop 

articles are also displayed 

in the context of product 

families to give customers 

a comprehensive overview 

of related or similar 

articles. 

In order to avoid displaying 

the same article in different 

versions - e.g. size, 

color - several times during 

the search, these related 

product variants are now 

displayed as such. The article 

that best matches your 

search within the variant 

articles now appears. This 

leads to the fact that with 

When you click on the 

button, you will be redirected 

to the product detail 

page directly to the product 

variants. 

the search for „resistance“ 

now not many very similar 

articles e.g. from the same 

manufacturer series are 

indicated, but always only 

one representative of this 

product family. You can recognize 

that articles belong 

together by the fact that the 

article is marked with the 

„more variants“ button. 

Here you can conveniently 

filter within the variants 

as you are already used 

to from the search results 

page. This function is 

particularly practical, for 

example if you like a manu- 

facturer‘s series and want 

to buy different products 

from this series. Normally, 

these articles are maintained 

as variants by our 

product managers and can 

be found easily and quickly. 

The filter will only show the 

matching value including 

the number of products 

with that searched value in 

our assortment. One click 

on it and the filter will be 

applied immediately - the 

search result or the articles 

within the selected 

category will contain only 

those with the desired filter 

value.

WITH UNIQUE SEARCH 

ENTRY 

On the other hand, if you 

are looking for a specific 

product, we make it as 

easy as possible for you. 

By entering the exact 

part number or Bürklin 

number, the search will 

lead you directly to the 

desired product. Searches 

with wildcards, such as by

BMV ELEKTRONIK FERTIGUNG GMBH 

COOPERATION 

AT EYE LEVEL FOR 

OVER 30 YEARS 

The many satisfied customers have 

remained loyal to BMV for decades 

and swear by the flexible and committed 

service as well as the high 

quality required of an ISO 9001 certified 

manufacturing company. 

Also due to the support through 

Bürklin Elektronik, BMV was able 

to maintain production without interruptions 

even in the event of delivery 

bottlenecks and component availability 

problems. 

BMV supplies customers from a 

wide range of industries, including 

medical technology, mechanical 

engineering, aerospace, nuclear 

power, automotive and many more. 

Due to steadily increasing demand, 

BMV has worked on further expanding 

SMD production in recent years. 

After the PCBs have been assembled 

with the modern automatic assembly 

machines, they are gently soldered 

in a vapor phase. This is followed 

by a final inspection using an AOI 

system to ensure consistent and 

flawless quality. 

At the customer‘s request, flux 

residues and other impurities can be 

removed from the circuit boards in a 

cleaning machine specially provided 

for this purpose. 

The BMV team is there for you every 

day with passion and full commitment 

to meet the demands of your 

products. 

SMD assembly, 

fast and flexible 

Expert assembly 

and wiring 

BMV Elektronik Fertigung GmbH 

was founded 33 years ago as a 

small medium-sized company in 

Martinsried near Munich. 

In the course of time, SMD and THT 

PCB assembly in pure and mixed 

form has been added to the former 

core competences of assembling 

THT PCBs, mounting and wiring 

assemblies. Another focus is the 

manufacture of cables. 

From the assembly of individual 

components to complete systems 

and control cabinets, BMV Elektronik 

Fertigung GmbH manufactures in 

small and medium quantities. On 

request, it tests assemblies according 

to customer specifications 

and creates the corresponding test 

protocols, which are both supplied 

and archived. 

Of course, the service also includes 

the procurement of components with 

special attention to speed, availability 

and the best possible prices. 

To ensure medium- and long-term 

supply security, the company offers 

agreed stock purchases of components 

and blanket orders. 

In order to meet the associated 

demands, it is essential to work 

together with reliable partners. 

From the very beginning, Bürklin 

Elektronik has supplied a very large 

proportion of components from a 

wide range of areas. These include 

measurement technology and tools, 

a wide range of active and passive 

components, cables and electromechanical 

components. 

The expert advice in the service 

department is always helpful at BMV, 

as is the reliably fast quotation system. 

If the standard delivery on the 

next working day is not sufficient, 

the local Bürklin Elektronik delivery 

service by courier is available for 

such unexpected situations. 

Cooperation at eye level is cultivated 

in the BMV production team just as 

it is with the suppliers. The focus is 

on long-term cooperation based on 

trust.

TDK 

TVS DIODES OFFER HIGHLY 

RELIABLE AND COMPLETE ESD 

PROTECTION SOLUTIONS FOR 

USB TM TYPE-C ® CONNECTORS 

Except for the four GND 

(ground) pins, ESD protection 

is needed on 20 pins. 

This protection is achieved 

by connecting small ESD 

protection TVS diodes from 

the pin to GND. If an ESD 

event occurs, these will redirect 

the transient current 

to GND. TDK TVS diodes 

are designed with a snapback 

feature with extremely 

low clamping voltage 

characteristics due to their 

“thyristor structure”. This 

feature helps to guarantee 

the reliable limitation of 

over-voltage. 

Pins are divided into three 

different functional groups 

based on pin functionalities, 

and three different 

TVS components have been 

developed accordingly. This 

ensures efficient and suitable 

protection, as shown 

in the following overview. 

The USB Type-C ® connector 

is the most common 

interface for computers, 

tablets and smartphones. 

It supports high-speed 

data transfer as well as 

fast charging of peripheral 

devices. Like other 

interfaces, USB TM Type-C ® 

connectors are frequently 

exposed to Electro Static 

Discharges (ESD), which 

may cause damage to the 

sensitive electronics of 

the connected devices. 

Therefore, connector pins 

must be properly protected 

against ESD. The layout 

and performance of USB 

Type-C ® connectors require 

specific ESD protection. 

TDK has developed Transient 

Voltage Suppressor 

(TVS) diodes, which are 

specifically designed to 

protect USB Type-C ® 

connectors. The TDK TVS 

portfolio provides the ideal 

solutions for the highspeed 

data pins up to 40 

Gbps using the fast USB TM 

4 40G protocol, as well as 

the Thunderbolt protocol. 

Furthermore, TDK TVS 

diodes support fast device 

charging via power delivery 

protocol and the respective 

pins. 

One of the handy features 

of the USB Type-C ® 

connector is its flippabiliy 

with no up or down orientation, 

which has been 

achieved by mirroring the 

pins on both sides of the 

connector. Figure 1 shows 

all 24 pins densely arranged 

without leaving 

much space for protection 

diodes. Additionally, 

the best practice for ESD 

protection is to place 

an ESD component as 

close as possible to the 

connector at risk of being 

exposed to the source of 

the transient event. Due 

to their miniaturized size, 

TDK TVS diodes fit perfectly 

into the application. TDK 

TVS diodes offer robust 

protection with minimal 

space consumption. All 

types comply with the IEC 

61000-4-2 system-level 

ESD standard. 

USB Type-C ® pin-out 

For super-speed Tx/Rx high 

data-rate pins, TDK offers 

ULC TVS diodes with low 

reverse working voltage 

(±3.3 V) and ultra-low 

capacitance. ULC TVS 

diodes have been tested 

and certified by an independent 

certification lab for 

applications with USB TM 4 

40 Gbps data rates and 

Thunderbolt TM signals. Test 

results show that TDK TVS 

protection diodes do not 

impair the communication 

signal on the lines. 

For the protection of the 

differential signal D+/Dpins, 

TDK offers TVS diodes 

with a working voltage of 

±5.5 V that are perfectly 

suited to USB 2 signal 

levels and that have a low 

parasitic capacitance. 

For VBUS power pins and 

neighboring CC (Configuration 

Channel) and SBU 

(Sideband Use) pins, TDK 

TVS diodes support reverse 

working voltages up to ±20 

V and fast charging functionality 

with a USB PD 

(USB Power Delivery) of up 

to 100 W with 5 A/20 V. 

The corresponding data 

sheets are available at 

Test reports and reliability 

reports are available upon 

request.

HELLERMANNTYTON 

HEAT SHRINK TUBING: 

WITH EXPERTISE THROUGH 

THICK AND THIN 

From coloured and transparent heat shrink with or without adhesive to heat shrinkable moulded parts: 

HellermannTyton, the cable management specialist, offers a comprehensive range of heat shrink products 

in a variety of styles and sizes that meet the highest standards. 

Heat shrink tubing is used when assembling cable sets. 

For example, to insulate the wires or cables, to provide 

additional mechanical protection or to mark them. There 

are five basic parameters that are decisive for the success 

of a heat shrink application: 

1. THE WALL THICKNESS 

In general, a distinction is made between thin-, medium- 

and thick-walled shrink tubing. The variants with an 

inner layer of adhesive are often referred to as doublewalled. 

The material thickness should be stated in mm 

after complete shrinkage. 

„Nominal“ means dimensions without any tolerances. 

2. THE DIAMETER 

For thin-walled heat shrink tubing, the diameter is 

usually given in inches; 25.4 mm equals 1 inch. 

3. THE RATE OF SHRINKAGE 

The shrink ratio indicates how much the product 

shrinks, i.e. the supplied expanded diameter in relation 

to the diameter after shrinking. The shrink ratio varies 

from 2:1 to 6:1. The higher the ratio, the greater the range 

of applications that the tubing can cover. As a result, 

fewer shrink tubing sizes are usually needed. 

4. THE LENGTH CHANGE 

Heat shrinkable tubing not only shrinks in diameter, 

but also in length. The so-called longitudinal shrinkage 

is given as a percentage. 

5. THE RIGHT SIZE 

Select the tubing size so that a minimum shrinkage of 

20 % and a maximum of 80 % is possible. 

MEDIUM WALL MA47 HEAT SHRINK TUBING 

with inner adhesive offers reliable protection against 

moisture and other environmental influences. With a 

generous shrinkage rate of up to 4:1, it is particularly 

suitable for low voltage applications above and below 

the ground. MA47 is available in 11 sizes from 8 mm to 

140 mm, supplied in 1 m lengths. 

THIN-WALLED HIS HEAT SHRINK TUBING 

is designed for everyday use. The HIS range is available 

with or without an inner layer of adhesive. It is available 

in various colours and with shrink ratios of 2:1 and 3:1. 

The handy dispenser boxes with small reels are particularly 

useful for electrical repairs. 

DOES THE TUBING FIT? 

Not sure if a ece of heat shrinkable tubing will fit your 

application? Simply enter the required dimensions into 

the HellermannTyton online heat shrink calculator. 

It will then suggest the right size for you. 

HOW THICK DOES THE WALL REMAIN? 

When at shrink tubing is processed, both the diameter 

and the wall thickness change. This online wall thickness 

calculator helps you to determine the theoretical 

wall thickness for a specific diameter.

FULL FLEXIBILITY 

FOR PORTABLE HEAT SHRINKING 

HOT TIPS FOR PERFECT HEAT SHRINKING 

Start the shrinking process in the middle of the tube. 

From there, move outwards to one end and then again 

from the middle to the other end. This way you avoid 

trapping air under the tubing. 

Shrink tubing also shrinks in the longitudinal direction, 

i.e. it becomes shorter overall when shrunk. You should 

take this shrinkage rate into account when cutting 

sections. 

If the object to be wrapped is heat conductive, make 

sure to preheat the object to avoid “cold spots“. This 

will ensure a tight and smooth fit. 

When cutting heat shrink tubing to the desired length, 

take special care to cut the ends smoothly. Poorly cut 

and irregular ends can cause heat shrink tubing to tear 

during shrinking. 

When selecting the tubing size, it is important to follow 

the 80:20 rule. Select the size so that it can shrink by at 

least 20% and at most 80%. 

DON‘T FORGET 

With the brand new CHG900 cordless heat gun, shrinking 

on the go is a joy. 

FASTER RESULTS WITH THE CORDLESS ALL-ROUNDER 

The CHG900 is a gas hot air blower designed for shrink 

applications where no power source is available or full 

mobility is desired. It is also suitable for soft soldering, 

plastic moulding or defrosting. 

The handy tool generates instant, adjustable heat from 

190 °C up to 900 °C and produces no open flame. It provides 

1.5 hours of operation per cartridge, even at low 

air temperatures around -8 °C. Only after 60 minutes of 

continuous operation is a short rest period of 15 minutes 

required to allow the internal components to cool 

down and avoid damage. 

No battery-powered hot air tool offers this much autonomy 

for heat shrinking. Its operating time depends 

on the number of shrinking processes, the shrinking 

temperature and the shrinking time. 

But with a full gas cartridge, the CHG900 works reliably 

for about 90 minutes regardless of the number, temperature 

and duration of the shrinkages. The charging 

time of a battery-powered device usually takes longer 

than the cooling time of the CHG900. 

LIGHT AND HANDY 

The CHG900 weighs only 555 g including a full P445 gas 

cartridge. This makes it one of the lightest hot air guns 

on the market. The gas cartridges, as well as critical 

spare parts such as the piezo ignition and the gas nozzle, 

can be replaced quickly and without additional tools. 

The empty cartridges are also fully recyclable. 

The CHG900 can be placed securely in a stable position 

for horizontal or vertical heat flows. The integrated 

stand frees up both hands for maximum control when 

shrinking. 

During shrinking, always ensure that the workplace is 

well ventilated and that you wear personal protective 

equipment such as gloves and safety goggles. 

Use a heat gun that has a secure stand on the workbench 

so that you can work on the shrink application 

with both hands.

MENTOR 

M-FIBRE – INNOVATIVE 

SIDE LIGHT FIBRE FOR 

PRODUCT-INTEGRATED 

LIGHT SOLUTIONS 

M-Fibre detailed view: 

The system consists of 

a sidelight fibre and sheath, 

an LED driver, a mixing 

optic integrated in 

the RGB module and 

matching LED modules. 

MENTOR, one of the leading specialists in productintegrated 

light, is extending its technology range for 

customised light solutions with the addition of M-Fibre, 

a new side light fibre system. 

M-Fibre system consist 

of the actual fibre, compact 

yet highly efficient 

LED-modules and the 

matching drivers. MENTOR 

offers the M-Fibre system’s 

individual components on 

stock or as customised 

applications, which will be 

deigned and manufactured 

according to the customer’s 

specific requirements. 

The standard range includes 

different fibres for 

different lengths of illumination 

(250 mm to 3,000 

mm). Up to an illuminated 

length of 1,500 mm only 

one LED module is required, 

for greater lengths 

the application of two 

modules is recommended. 

In terms of performance 

the customers may choose 

between two options, as 

well as either a white or 

RGB-LED module. Inside 

the LED module a precision 

optic ensures a perfect 

mixing of the designated 

colour, as well as enabling 

premium light quality and 

greatest efficiency thanks 

to focussing the light 

beams in an ideal way. 

The fibres used for the 

M-Fibre are thin, flexible 

and allow small bend radii 

– all the while effectively 

providing homogenous 

luminance without visible 

colour deviations with a 

radiation angle of 360°. 

To ensure this, polymer optical 

fibres (POFs in short) 

made of PMMA are activated 

by supplying them with 

a light-dispersing surface 

structure. Afterwards the 

fibres are bundled and 

coated with a diffused 

cover. 

Depending on the application, 

the fibres can be 

activated across the entire 

length or only partially. 

With partial activation, only 

specific areas of the side 

light fibre are lit up in a 

targeted and loss-optimised 

manner. This prevents 

undesired scattered 

light and optimises the 

efficiency of the integrated 

lighting system. With this 

technology, multi-coloured 

applications and running 

lights or similar dynamic 

lighting scenarios are also 

possible. 

In connection with single or 

multi-coloured LED modules 

for one or two-sided 

lighting, M-Fibre allows for 

lighting solutions that are 

optimised to the installation 

space and can be 

installed flexibly over a 

length of several metres. 

Thanks to the modular structure, the replacement of the fibres 

or the LED module for after-sales service is quick and easy. 

An integrated mixing lens inside the RGB colour modules 

ensures good colour mixing and a consistent colour impression 

across the entire length.

23

Unlike other POF solutions 

available on the market, 

M-Fibre is not available 

as rolled goods or standard 

solutions, but is a 

lighting system in which 

all individual components 

are optimally tailored to 

the respective customer 

requirements. In addition to 

the system’s high flexibility 

and outstanding light 

quality, other advantages 

of the new, largely toolfree 

technology, are the 

low initial costs and short 

development times. 

The new side light fibre 

gives product designers 

and developers multiple 

ways of achieving functional 

yet decorative linear 

lighting or indirect ambient 

lighting. Integration in 

freeform surfaces is also 

easily possible. Through 

the spatial separation of 

the light source and the 

light emitting surface, 

M-Fibre can also be used 

under water, in explosion 

protection areas and in the 

food industry. 

The fields of application 

for high-quality, productintegrated 

light of this 

kind are wide-ranging. 

The automotive, Smart 

Clothing / Smart Luggage 

and mechanical engineering 

sectors, building services 

engineering, residential 

and office furniture or 

domestic appliances and 

safety technology are just 

a few examples.

ESD - THE INVISIBLE DANGER 

WHAT DOES ESD MEAN? 

ESD stands for electrostatic discharge. 

It is caused by the sudden 

equalization of charge between objects 

with a different charge potential. 

This discharge can generate a 

large amount of electrical current. 

SOURCE

the carpet

HOW IS ELECTROSTATIC 

CHARGE GENERATED? 

Every object has positive and negative 

elementary particles. Positive 

and negative charges normally neutralise 

each other. Objects are electrically 

neutral. However, if an object 

loses electrons, an imbalance arises. 

This imbalance is called the charge 

potential. Charged objects have a 

tendency to equalise by discharging. 

In the event of a sudden discharge, 

high currents flow in a small electronic 

component. 

ELECTROSTATIC DISCHARGE 

IN EVERYDAY LIFE 

The most visible form of electrostatic 

discharge is lightning during a storm, 

when clouds with different potentials 

abruptly discharge. All of us have 

at one point experienced a sudden 

discharge, such as after walking 

across a carpeted floor and then 

touching the handle of a door.

COMPONENT SENSITIVITY 

The ESD sensitivity of electronic 

components is rising as component 

parts are increasingly miniaturised. 

Moreover, ever smaller components 

offer less and less space for protective 

circuits on microchips. In order 

to save energy, components need to 

get by on less power. A discharge 

of just 50 volts is enough to cause 

damage to a blue LED, for example. 

SMDs are already at risk of damage 

at voltages higher than 100 V. In 

contrast to this, the human ability to 

perceive ESD is very limited. 

Discharges are first noticeable from 

3500 volts, audible from 4500 volts 

and visible from 10000 volts. 

DETECTING AND ELIMINATING 

FAULTS 

Components damaged by ESD cannot 

normally be seen with the naked 

eye. Even tiny discharges can lead 

to complete failure. These direct 

failures can usually be identified 

during quality control. So-called 

latent failures are especially critical, 

as they only become apparent when 

products are in operation. The time 

and effort needed to eliminate these 

intrinsic failures cause the greatest 

costs. ESD damage generally concerns 

latent damage. It is therefore 

absolutely essential that the appropriate 

precautions are taken.

MEASUREMENT OF RESISTANCES 

IN THE ESD AREA 

In addition to surface resistance, 

the following resistances are also 

important: the bleeder resistance 

(resistance against earth/protective 

conductor), volume resistance (resistance 

measured at opposite points 

of a material) and point-to-point 

resistance (resistance between two 

electrodes). 

PERSONS AND WORKPLACES 

EQUIPMENT 

If ESD-sensitive components are 

being handled, people and workplace 

equipment need to be ESD compliant. 

The primary focus for people 

is ESD-compliant clothing (shoes, 

coats, antistatic wrist straps), for 

workplace equipment, conductive 

flooring is just as important as 

ESD-compliant workbenches and 

chairs. The most important measure 

is the proper grounding of personnel. 

ESD COMPLIANT TOOL 

ESD-compliant tools are also just as 

important. In the Bernstein catalogue, 

you will find a comprehensive 

range of ESD-compliant tools for 

use in ESD protected areas. Often 

work needs to be performed outside 

of these protected areas, in which 

ESD-sensitive components need to 

be installed. We offer solutions here 

too, which are suitable for mobile 

use, such as table covers, grounding 

plugs for power sockets, clamping 

equipment and hand tools

KNIPEX 

CRIMPING TOOLS: 

SAFE AND COMPLIANT 

WITH STANDARDS 

FOR THE PRODUCTION OF ELECTRICAL CONNECTIONS 

ELECTRONIC PLIERS: 

COMPACT AND POWERFUL 

FOR CUTTING AND GUIDING ELECTRONIC COMPONENTS 

With the rapid increase 

in electric drives and the 

necessary control electronics, 

the need for fast 

and at the same time safe 

connections is growing. 

Connector types such as 

Scotchlok connectors, 

Western connectors, modular 

connectors, Cannon 

connectors and many more 

are suitable for crimping 

- i.e. pressing in which 

the connection is made by 

using a compression tool. 

The complexity of possible 

crimp connections is 

constantly increasing. In 

addition to flexible and solid 

wires, fibre optic cables, 

antenna cables, telephone 

and LAN cables and many 

other types of cables can 

now also be processed with 

crimping tools. 

KNIPEX offers a wide range 

of solutions for the safe 

and standard-compliant 

connection of cables and 

connectors. From the inexpensive 

wire end crimping 

pliers as a light and 

compact hand tool to the 

universal crimping system 

pliers Multi-Crimp® 

to the semi-automatic 

electrically driven eCrimp 

system pliers with over 

1,500 interchangeable, 

different crimping sets - 

at KNIPEX the user has all 

the options in your hand. 

And innovative support 

to boot. For example, 

universally adjustable 

positioning aids or electronic 

displays for wear 

and necessary calibration 

for crimping pliers for very 

sensitive crimp connections. 

CRIMPZANGES 

IN DIFFERENT VERSIONS 

Due to the large number 

of different plug connections, 

crimping pliers are 

required in many different 

versions. As a rule, these 

pliers are operated with 

one hand - for particularly 

large conductor crosssections, 

however, there 

are also models that facilitate 

two-hand operation 

due to their favourable 

design. 

A battery-operated version 

is also available. Versatility 

is also demonstrated by 

models that are suitable 

not only for crimping but 

also for stripping and cutting 

cables. 

FERRULES PLIERS 

A wire end ferrule pliers 

exerts pressure on the wire 

end ferrule and wire from 

all sides via four crimping 

parts. The resulting plastic 

deformation in the respective 

crimp profile leads to 

a mechanically strong and 

electrically safe connection. 

SELF-ADJUSTING 

CRIMPING PLIERS 

Crimping pliers that are 

able to automatically 

adjust to the crosssection 

of the sleeves to 

be processed have been 

developed especially for 

the professional sector. 

This guarantees the use of 

the correct crimping jaws 

at all times - which makes 

crimping faster and more 

comfortable. 

FOUR-PRONGED 

CRIMPING PLIERS 

Particularly demanding 

plug connections are found, 

for example, in areas such 

as the automotive industry, 

aviation or medicine. 

Here, turned contacts are 

required. 

Four- mandrel crimping 

pliers are capable of producing 

these high-quality 

crimp connections. Four 

synchronously running jaws 

evenly press a mandrel 

profile into the connector. 

Electronic pliers do not 

differ significantly from 

normal pliers except for 

their smaller size. The 

most common designs due 

to the intended use are as 

follows are the side cutters 

and gripping pliers. 

KNIPEX offers special 

tools for cutting wires and 

components on circuit 

boards: electronic side 

cutters with a wide range 

of head, cutting edge and 

bevel shapes. 

Special care must always 

be taken where electronics 

and sensitive components 

are involved. 

That is why many pliers are 

also available as ESD tools. 

ESD is the abbreviation for 

„electrostatic discharge“ 

- the discharge of small 

voltage breakdowns that 

can quickly cause serious 

damage to electronic components. 

By using ESD pliers, the 

hardware is protected 

because the circuit can 

flow and is not blocked, so 

that voltage surges cannot 

occur. 

With their often delicate 

construction, electronic 

pliers are sensitive to mechanical 

overload. Therefore, 

they should always be 

used with due respect for 

the delicate nature of these 

pliers. The maximum wire 

diameters printed on the 

handles of cutting pliers 

must be observed. 

The particularly high-quality 

precision electronics 

pliers are made of ball 

bearing chrome steel, 

which ensures the highest 

possible load capacity for 

these filigree pliers. 

SPECIAL ADVANTAGES 

OF THE KNIPEX 

ELECTRONIC PLIERS 

Thanks to a series of 

extensive changes in the 

range of pierced electronics 

pliers, KNIPEX Elektroniktool, 

which has once again 

significantly improved the 

outstanding properties of 

its predecessors. 

From the classic side cutters 

to end cutters, diagonal 

cutters and flat nose 

pliers: KNIPEX electronic 

pliers are now even more 

durable, more powerful and 

with even more sensitivity. 

By using ball bearing 

chrome steel in the entire 

family of box joint electric 

pliers, KNIPEX offers tools 

that provide the most 

accurate feedback from the 

pliers tip to the handle due 

to their bending behaviour. 

It is precisely there that 

an optimally designed 

single-component shell 

now ensures exceptional 

handiness in the slimmest 

handle variants. 

Thanks to the use of new 

manufacturing processes 

and optimised materials, 

the end cutters not only 

score with slim handles, 

but also with slimmer 

heads. This makes it even 

easier to reach through in 

narrow working environments. 

Last but not least: Both 

the single- and two-component 

sleeves have a much 

slimmer design in the front 

area, so that the pliers can 

be guided very sensitively 

with the thumb and forefinger. 

The cutting behaviour 

of the pliers has once 

again been significantly 

improved by changing the 

geometries and transmission 

ratios. The resulting 

savings in force are another 

convincing argument for 

choosing KNIPEX.

SCHURTER 

SAFE CHARGING 

AT HOME 

Electric vehicles are powered by lithium-ion battery packs. Although they are used in billions of applications 

worldwide from cars to the latest cell phones, they are sensitive constructions. However, if care is taken during 

the charging process the battery life and safety can be significantly increased. 

If you are thinking about buying an electric vehicle, it 

makes sense to consider at an early stage how this vehicle 

should be supplied with energy. In the vast majority 

of cases this will involve charging at home. That is why 

we want to limit ourselves to this point in this article. 

What do we need to look out for? 

DURATION OF THE CHARGING PROCESS 

The calculation for the loading time is done quickly. Take 

the battery capacity of a vehicle in kWh and divide it by 

the power (kW) of the charging station. This gives you 

the number of hours for a full charge. 

THE WEAKEST LINK DETERMINES THE PACE 

During the charging process always keep in mind that 

it consists of the mains supply, the charging station, 

the charging cable and the charger, just like a chain. 

The weakest link of such a chain always determines the 

maximum charging power. Thus, if the charger only has 

a capacity of 6.6 kW, it does not be of any help to „pump“ 

some current into the batteries with a 22 kW charging 

station. 

FAST CHARGING SHORTENS SERVICE LIFE 

Fast charging harms every lithium-ion battery. Charging 

and discharging lithiumion cells can lead to lithium 

plating. Lithium ions are deposited on the anode surface 

instead of nesting between the layers of graphite. This 

effect leads to significant losses in performance, service 

life and safety. In extreme cases, lithium plating can 

even lead to a short circuit or since metallic lithium is 

highly flammable, to a fire. 

CHARGING ON 1-PHASE MAINS 

The smallest available wall charging stations are 

connected to the 230 V/16 A household mains supply. 

These wall charging stations can only be used for 

single-phase charging up to about 3.6 kW. This is only 

practical in a few cases. For example, vehicles with low 

battery capacity for short distances or plug-in hybrids 

that do not rely exclusively on the electric motor. 

CHARGING ON 3-PHASE MAINS 

A large number of wall charging stations for the private 

sector are connected to 400 V/16 A three-phase current 

(11 kW max. charging capacity). Practically every household 

offers this possibility without additional changes to 

the power supply system. This already reduces the 

charging times by a factor of 3. The simple design of 

these wall charging stations is particularly advantageous, 

as in addition to 3-phase charging, the standard 

on-board chargers can also be operated at 230 V (max. 

3.6 kW) on one phase without further fusing. 

If you need more power, you have to upgrade the power 

supply. For example, to a stronger wall charging station 

with 400 V/32 A (22 kW) or 400 V/63 A (44 kW). However, 

you are dependent on the help of a specialist for this. It 

is also imperative to clarify the technical (existing electrical 

load) and legal (tenants, owners) feasibility. In return, 

such powerful chargers offer significantly shorter 

charging times. Again, the performance of the built-in 

on-board charger determines the charging capacity that 

can ultimately be achieved. 

INTELLIGENT CHARGING MANAGEMENT 

Performance is one thing. It is at least as important to 

use this power intelligently and safely. High-performance 

electronics are responsible for this. The charging 

management of the wall charging station communicates 

with the vehicle‘s Battery Management System (BMS). 

BMS are responsible for controlling and monitoring the 

charging and discharging process. Their main task is to 

ensure that each individual cell neither during charging 

nor discharging falls below nor exceeds a State of 

Charge (SoC) limit value defined for the application. The 

SoC value describes the remaining available capacity of 

a battery in relation to its nominal value. 

ELECTROMAGNETIC COMPATIBILITY (EMC) 

Today, high-performance electronics always means 

high-clocked circuits. And these fast circuits always 

carry the risk of excessive emissions of electromagnetic 

interference signals, which must be reduced. This problem 

can be overcome with EMC filters with high attenuation 

and a clever circuit board layout - in the 1-phase 

range usually even with discrete components. 

SCHURTER has a wide range of chassis mount filters 

for both 1-phase and 3-phase systems. Whether 1- or 

2-stage filters are (must be) used depends on the 

strength of the interference signals, which should be 

measured in advance. For almost any interference signal 

and any power range, the problem of electromagnetic 

compatibility can be solved in a compact way.

PROTECT! 

Last but not least – charging stations perform the lion‘s 

share of their service unattended. Generously dimensioned 

protection with high-quality passive components 

(fuses, fuseholders) helps to prevent major damage 

such as a fire in advance. An example of this would be 

the CSO highperformance clip for 10.3 x 38mm fuses. 

Due to the use of a special copper alloy, it is characterised 

by a particularly high clamping force. This results 

in minimal power dissipation, which is particularly 

essential for applications with high currents. With a typical 

contact resistance of ≤ 1 mΩ it is ideally suited for 

use in e-mobility charging stations (AC and DC). 

IATF 16949: EXPERIENCED PARTNER 

SCHURTER has been certified according to IATF16949 

for many years and serves a large number of customers 

with fuses that have been tested according to AEC-Q200 

for various applications (battery management, climate 

control, engine-related electronics for diesel/petrol 

engines, etc.). Millions upon millions of fuses for protection 

against overcurrent and overtemperature are 

in use worldwide. The close networking with international 

automotive organizations and the industry itself 

make SCHURTER a competent partner for all questions 

concerning the protection of electronics in automotive 

engineering including charging stations. For decades 

SCHURTER has had a competence center for EMC solutions 

in Switzerland, which develops customized solutions 

for industrial, medical and other applications.

BOURNS 

FULLY INTEGRATED 

ISOMOV 

HYBRID PROTECTOR 

INTRODUCTION 

Bourns is pleased to announce its 

groundbreaking lineup of IsoMOV 

hybrid protection components. By 

combining the best features of the 

breakthrough surge performance 

EdgMOV technology with an integrated 

Gas Discharge Tube (GDT) 

isolation structure, the IsoMOV 

protector offers high reliability and 

long life including in certain harsh 

environments. 

The IsoMOV Hybrid Protector Series 

is an upgrade to nearly any MOV 

power application where premium 

performance and/or space savings 

are valued. The extended temperature 

range, low leakage and superb 

energy handling density are especially 

advantageous to industrial and 

other applications exposed to high 

surges. 

The IsoMOV device‘s unique and 

graceful end-oflife failure mode 

quickly and cleanly blows the line 

fuse, never leaving equipment unprotected 

and eliminating the need 

for any indicator circuitry. 

The IsoMOV protector family of 

products includes three unique series 

of devices; Model IsoM3, IsoM5 

and IsoM8. With nominal surge 

ratings of 3 kA, 5 kA and 8 kA, these 

revolutionary new protectors offer 

performance usually found in larger 

traditional MOV devices. 

UNIQUE CONSTRUCTION 

The IsoMOV protector fully integrates 

the classic GDT and MOV in a 

symbiotic relationship, enhancing 

reliability and performance. In this 

configuration, the GDT blocks leakage 

currents through the MOV that 

would otherwise lead to premature 

failure of the MOV device, while the 

MOV prevents the follow-on current 

(after a surge) that might damage 

the GDT.

the GDT. 

In fact, the surge ratings of IsoMOV 

protectors are comparable to the 

surge ratings of the next larger size 

of conventional MOV devices. This 

offers designers the flexibility of 

choosing an IsoMOV protector that 

is smaller than the MOV option or 

choosing an IsoMOV protector of 

the same size as the MOV option and 

enhancing the surge capability of 

their protection scheme.
