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. 3" 2.88" ø 1.13" RESISTANCE TO PULSE 0.80% PERFORMANCE CHARACTERISTICS DC 20KV see circuit for test conditions OY Series 0.60% Test Max Working Voltage Dielectric Strength Max Overload Voltage Max Pulse Voltage1 Pulse Tolerance, 100 pulses ∆R/R 10 Kohms 0.40% 1 Kohm 0.20% 100 ohms 0.00% 0 0.80% 100 1,000 Cycles 10,000 ∆R/R 10 Kohms 0.40% 1See 0.20% 0.00% 100 1,000 Cycles 10,000 O R D E R I N G I N F O R M AT I O N RoHS Compliant 20,000 ������� 1 sec. on / 1 sec. off 10 kohm Max.
