Metal Oxide Varistors RGA Varistor Varistor’s are voltage dependent, nonlinear devices which have an electrical behavior similar to back-to-back zener diodes.
RGA series zinc oxide varistors are nonlinear resistors, consisting mainly of zinc oxide and several kinds of metal oxide additives.
They are bilateral and symmetrical V-1 characteristics curve and unparalleled large peak current capabilities are used for absorption of transient voltage, suppression of pulse noise and circuit voltage stabi
