OW/OX/OY SERIES DATASHEET

Ceramic Composition 10% Tolerance

OY series product image

 

The OW/OX/OY 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 OW/OX/OY resistors can often replace carbon composition resistors which can be difficult to source.

 

Features

  • Replaces 1 and 2 watt carbon composition resistors
  • Meets high energy density demands
  • High peak power
  • 10% Tolerance
  • Non-Inductive
