!Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.• This catalog has only typical specifications. Therefore, please approve our product specifi cations or transact the approval sheet for product specifi cations before ordering.C85E.pdfApr.7,2014Safety Certified Ceramic Capacitors for Automotive Noticec Notice (Soldering and Mounting)Cleaning (ultrasonic cleaning)To perform ultrasonic cleaning, observe the followingconditions.Rinse bath capacity: Output of 20 watts per liter or less.Rinsing time: 5 min. maximum.Do not vibrate the PCB/PWB directly.Excessive ultrasonic cleaning may lead to fatiguedestruction of the lead wires.c Notice (Rating)1. Capacitance Change of CapacitorsCapacitors have an aging characteristic, wherebythe capacitor continually decreases itscapacitance slightly if the capacitor is left onfor a long time. Moreover, capacitance mightchange greatly depending on the surroundingtemperature or an applied voltage. Therefore,it is not likely to be suitable for use in a constanttime circuit.Please contact us if you need detailed information.2. Performance Check by EquipmentBefore using a capacitor, check that there is noproblem in the equipment's performance and thespecifi cations.Generally speaking, CLASS 2 ceramic capacitorshave voltage dependence characteristics andtemperature dependence characteristics incapacitance. Therefore, the capacitance value maychange depending on the operating condition in theequipment. Therefore, be sure to confi rm theapparatus performance of receiving infl uence inthe capacitance value change of a capacitor,such as leakage current and noise suppressioncharacteristic.Moreover, check the surge-proof ability of acapacitor in the equipment, if needed, because thesurge voltage may exceed specifi c value by theinductance of the circuit.80
