Varistors - CNR
Description
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.
Applications 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 various kinds of relays and electro-magnetic valves.
● Electrostatic discharge an spike noise suppression.
● Protection of various kinds of transistors, diodes, ICs, thyristors, triac semiconductors, and etc.
● Automobile control system such as transistorized ignition system and electronic fuel injection system, and etc.
