The OX/OY Series of fixed ceramic resistors are ideal for circuit-
ry 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 OX/OY resistors can
often replace carbon composition resistors which can be difficult
to source.
