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