Overview

APPROVAL SHEET CeNtRa Varistor 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.

Key Features

  • Surge Protection in consumer electronics.
  • Fast response -- industrial electronics.
  • Excellent voltage ratio -- telephone and telecommunication systems.
  • High stabilization for circuit voltage -- automobile equipments.
  • Unparalleled absorption for transient voltage -- measuring and controller systems characteristics -- electronic home appliances.
  • Bilateral and symmetrical V-I Characteristics -- gas and petroleum appliances curve.
  • Absorption of switching surge from.
