Varistor Specification

TYEE Varistor

Varistor are voltage dependent, nonlinear device which have an

electrical behavior similar to back-to-back zener diodes.

TYEE 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.
