Transient/Surge Absorbers
Transient Voltage Surge Suppressors
CeNtRa Varistor
Varistor are voltage dependent, nonlinear device which have an
electrical behavior similar to back-to-back zender 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.
