SVR varistors for low voltage ratings

1) Features

- UL and VDE safety approvals.
- Varistor voltage range : 18 to 68V (10%).
- Lower clamping voltage for better surge protection.
 

2) Recommended applications

- Semiconductor device (TR, Diode, IC, Thyristor or TRIAC etc.) protection.
- Surge protection in consumer electronics.
- Surge protection in communication, measuring or controller electronics.
- Surge protection in electronic home appliances, gas or petroleum appliances.
- Motor, Relay or electromagnetic valve surge absorption.

3) Electrical characteristics

Operating temperature range : - 40 ∼ 85℃
Storage temperature range : - 40 ∼ 125℃
Temperature coefficient of varistor voltage : 0 ∼ - 0.05%/℃
