CNR-20D181K Datasheet | CNR

APPROVAL SHEET Ce Nt Ra Varistor Varistor are voltage dependent, nonlinear device which have an electrical behavior similar to back-to-back zener diodes. CNR series zinc oxide varistor are nonlinear resistors, consisting main of zinc oxide and several kinds of metal oxide additive. They are bilateral and symmetrical V-I characteristics curve and unparalleled large peak current capability are used for absorption of transient voltage, suppression of pulse noise and circuit voltage stabilization. Applications Features - Surge Protection in consumer electronics - Fast response -- industrial electronics - Excellent voltage ratio -- telephone and telemunication systems - High stabilization for circuit voltage -- automobile equipments - Unparalleled absorption for transient voltage -- measuring and controller systems characteristics -- electronic home appliances - Bilateral and symmetrical V-I Characteristics -- gas and petroleum appliances curve - Absorption of switching surge from various kinds of relays and electro-magnetic valves. - Electrostatic discharge an spike noise suppression. - Protection of various kinds of transistors, diodes, ICs, thyristors, triac semiconductors, and etc. - Automobile control system such as transistorized ignition system and electronic fuel injection system, and etc. Related Standards - UL1414, UL1449(2nd Edition), CSA, VDE Explanation of Part Numbers CNR mon Code Ce Nt Ra Zinc Oxide Varistor Type Disc Type Tolerance K:±10% Suffix code Element Dia. 07 - ψ7.0mm Varistor Voltage 271=27X101=270V Space:Standard Straight lead/Bulk Packing TRS:Straight lead/Tape&Reel Packing TRK:Type I Crimped lead/Tape&Reel Packing TIK:Type II Crimped lead/Tape&Reel Packing TRH:Type III Crimped lead/Tape&Reel Packing BTS:Straight lead/Flat Box Packing BTK:Type I lead/Flat Box Packing A:Silver Disc BTI:Type II lead/Flat Box packing BTH:Type III lead/Flat Box Packing TTS:Straight Cut Lead /Bulk Packing TTK:Type I Cut Lead /Bulk...
