Introduction

Part Name

   Surge suppression varistors

 

◆Features

1. Size small, through-flow capacity and a large quantity of energy resistance

2. Epoxy encapsulated insulation, good Weather resistance

3. Quick response time: <25ns

4. Wide use of ambient temperature: -40 ~ +85

5. Insulation Resistance high: 500

6. High-efficiency voltage transient absorption

7. Ultrashort time Surge voltage response time

8. Substantial instantaneous energy absorption capacity

9. Lower clamp voltage than the current flow and no stagnation

 

◆Applications

1. Transistors, diodes, IC, thyristor and semiconductor switching elements and a variety of electronic equipment over-voltage protection

2. Household appliances, industrial electrical, relays and electronic valve surge absorption

3. Electrostatic discharge and noise signal to eliminate

4. Leakage protection, switching surge voltage absorbing

5. Telephones, communications equipment, such as program-controlled switchboard surge absorption
