While not able to handle the same pulse energy as carbon comps or wirewounds, metal oxides offer better pulse handling than standard metal film resistors. Stackpole’s RSF / RSMF metal oxides have power ratings up to 5W and working voltages up to 1,000V. The RSF / RSMF is flameproof and meets UL 94V-0.
The RSF / RSMF is a good choice for power supplies, LED lighting, power generation controls, HVAC controls, oven and spa controls, and industrial and electro-mechanical controls.
Pricing for the RSF depends on size, resistance value, and tolerance.
