OC Series Datasheet

Ceramic Composition 10% Tolerance

Res Oc Product Image

 

The OC Series of fixed ceramic resistors are ideal for circuitry associated with surges, high peak power or high energy. They offer enhanced performance in high voltage power supplies,R-C snubber circuits, and inrush limiters. The OC resistors can often replace carbon composition resistors which can be difficult to source. 

 

Features

  • Replaces 1 and 2 watt carbon composition resistors
  • Excellent alternative to the Ohmite OX/OY series
  • Meets high energy density demands
  • High peak power
  • 10% Tolerance
  • Non-Inductive
