OX/OY Series Ceramic Composition 10% Tolerance The OX/OY Series of fixed FeatureS ceramic resistors are ideal for • Replaces 1 and 2 watt circuitry associated with surges, carbon composition high peak power or high energy. resistors They offer enhanced perfor- • Meets high energy mance in high voltage power density demands supplies, R-C snubber circuits, and inrush limiters. The OX/ • High peak power OY resistors can often replace • 10% Tolerance carbon composition resistors which can be difficult to source.
