Description:
470V, 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.
Features:
1. Surge Protection in consumer electronics
2. Fast response — industrial electronics
3. Excellent voltage ratio — telephone and telecommunication systems
4. High stabilization for circuit voltage — automobile equipments
5. Unparalleled absorption for transient voltage — measuring and controller systems characteristics — electronic home appliances
6. Bilateral and symmetrical V-I Characteristics — gas and petroleum appliances curve
7. Absorption of switching surge […]
