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 -- [ ... ]
