TUL Zinc Oxide Varistor

 Varistor is a voltage dependent resistor. Whcich have symmetrial voltage-current  characteristics and unparalleled large peak  current capability are used for absorption of  transient voltage ,suppression of pulse noise  and circuit voltage stabilization.
1.Features
 Low leakage current
 Excellen voltage ratio.
 Wide voltage.
 Fast response time.
2.Application
 IC`semiconductor protection.
 Surge voltage protection in          communiction,measuring,and controller     elecronics.
 Surppression of main borne transients in industrial electonics and consumer     electronics.
