OX/OY Series
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.
