China wholesale Zinc Oxide Varistors - Zinc Oxide Varistor – Fayun Detail:

Metal Oxide Varistor/Zinc Oxide Varistor is non-linear resistor utilizing as semiconductor electrocnic ceramic element mainly composed of zinc oxide. It’s called varistor or mental oxide varistor(MOV), just as it is sensitive to voltage’s change. The body of varistor is a matrix structure composed of zinc oxide particles. The grain boundaries between particles are similar to the electrical characteristics of bidirectional PN junctions. When the voltage is low these grain boundaries are in the high impedance state and when the voltage is high they will be in the breakdown state which is a kind of non-linear device.

Features

1. Varistor voltage (47V-1200V)

2. Excellent non-linearity coefficient

3. Great withstanding surge current

4. Response time:<20ns

5. Diameter: 05D,07D,10D,14D,20D,32D,34S

Applications

* Transistor, diode, IC, thyristor or triac semiconductor protection.

* Surge protection in consumer electronics.

* Surge protection in industrial electronics.

* Surge protection in electronic home appliances, gas and petroleum appliances.

* Relay and electromagnetic valve surge absorption.
