CNR-18D751K

APPROVAL SHEET CeNtRa 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 telecommunication 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 Common Code CeNtRa Zinc Oxide Varistor 0 7 D Type Disc Type 2 7 1 K Tolerance K:±10% T...
