MOV ZOV Metal Oxide Varistor 7mm 470V 0.25W

Varistors are voltage-dependent, nonlinear devices that have an electrical behaviour similar to back-to-back Zener diodes. Zinc oxide varistors are nonlinear resistors, consisting main of zinc oxide and several kinds of metal oxide additives. 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.
