Raychem Multi Layer Varistors

Multi Layer Varistors are small, leadless, surface mount packages made of multiple layers of Zinc Oxide, with electrodes between them. They are used to help protect integrated circuits and other sensitive equipment. Their small size is ideal for high density printed circuit boards.

Tyco Electronics Circuit Protection also offers the “E” series which is a family of low capacitance MLVs. They are specifically designed to provide ESD protection in high data rate applications.

Part Numbering System for Multi Layer Varistors

 
  • Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
  • The devices are intended for protection against occasional overvoltage fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated.
  • Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic components.
