Ceramic Composition

10% Tolerance

The OX/OY Series of fixed

ceramic resistors are ideal for

circuitry associated with surges,

high peak power or high energy.

They offer enhanced perfor-

mance in high voltage power

supplies, R-C snubber circuits,

and inrush limiters. The OX/

OY resistors can often replace

carbon composition resistors

which can be difficult to source.
