OX/OY Series Ceramic Composition 10% Tolerance F e at u r e s 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. * Replaces 1 and 2 watt carbon composition resistors * Meets high energy density demands * High peak power * 10% Tolerance S ER I E S S P E C I F I C AT I O N S Series OX OY Watts max.* 1 2 * at 70C. **For a single impulse.
