Marking and Packaging Specifications for Radial-leaded Metal Oxide 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.
