IM-NF SeriesPCB MOUNTING SURGE PROTECTIONIEC category / EN type: C1/C2/C3 (IEC 61643-21)Design:OEM PCB moduleMode of protection:TransverseNumber of protected lines: 1Nom. Operating Voltage U n:5, 15, 24VDCMax. Operating Voltage U c:6, 18, 28VDCSeries Elements typical: 18Ω / 47µHFreq:< 0.6 - 1.4MHz (ref. Specification sheet)Surge Discharge Ratings: I n: 5kA 8/20µs, I max: 10kA 8/20µsSeries load current:145mAEnclosure:PCB hybridTerminals:PCB pinsThe IM-NF series is designed as a hybrid, PCB mount, protector against the effects of induced voltages onto data,signal and communication circuits. It is used by OEM as a component in their final product assembly.It consists of a multi-stage protector with coarse protection being provided by a two terminal gas discharge tubewhile fine protection is provided using a high speed silicon stage. Care is taken to ensure coordination betweenthese two stages without voltage or surge current blind spots occurring.Over current protection is provided by a PTC element, which provides a level of protection against short circuit ormains incursion. Internal thermal disconnectors are also employed to reduce the hazards of thermal runawayduring fault conditions.An inline inductor is incorporated and can be used to achieve better coordination with other on-board protectioncomponents.Technical characteristicsTypeProtection constructionNumber of protected pairsNominal operating voltageMax. continuous operating voltageRated spark overvoltageRated operating current at 25oCNominal discharge current (8/20µs)Residual voltage at 5kA (8/20µs)Response time of overvoltage protectionThermal protectionInsulation resistance of the protectionSerial capacitanceSerial inductanceTransverse capacitanceOperating temperatureDegree of protectionHousing materialMountingOrdering codeUnUcI LInt ARLCIM-NF5V 15V 24VProtective module1 (2 conductors)5 V DC 15 V DC 24 VDC6 V DC 18 V DC 28 VDC6.5 - 8V 20 - 24V 30 - 36V145mA 145mA 145mA5kA 5kA 5kA< 20V < 45V < 65V< 1ns < 1ns < 1nsThermal disconnection≤ 6 kΩ ≤ 18 MΩ ≤ 28 MΩ15 - 18Ω 15 - 18Ω 15 - 18Ω47m H 47m H 47mH< 10nF < 4nF < 3nF-40oC … +80oCIP 20Thermoplastic; gray, extinguishing degree V-Oon a printed circuit127 138 127 139 127 141Dimensional drawingsConnection diagram26 1027Legend:TDGDTLPTCcoeficientBDSGthermal decouplergas discharge tubecoilvaristor with a positivetemperaturebi-directional TVS diodesignal groundingTD1(In)GDT2(PG)PTC3(SG)BD4(Out 1)L5(Out 2)www.iskrazascite.si75
