Metal-Oxide Varistor

No Preview Available !

20D Series Metal-Oxide Varistor
Features
Wide range of operating voltages from 5 Vrms to 1000 Vrms (6 Vdc to 1465 Vdc)
Fast response time of less than 25ns, instantly clamping of transient over-voltage
Capable to handle high surge current
High energy protection capability
Low clamping voltages for efficient surge behavior
Low capacitance values, ideal for digital switching circuit protection
High insulation resistance, preventing electric arcing to adjacent components or
circuits
Application
Transistors, diodes, integrated circuits (IC), thyristors or Triac semiconductor protection
Surge protection for consumer electronics
Surge protection for industrial appliances
Surge protection for electronic home appliances, gas or petroleum operated appliances
Relay and electromagnetic surge absorption.
