Consult factory for other values Maximum Operating Voltage 350 VAC, 500 VDC through glass, 1000 VAC, 1500 VDC through substrate Overload Five times rated power, as long as the one second average dissipation does not exceed the wattage rat- ing. ∆R: ±2%, 2000 hours Derating 100% @ 25°C to 0% @ 180°C ambient. Ohmite’s original Power Chip resistors feature our thick film on alumina substrate technology. These planar packages yield space saving, 10W/in2 power densities that require over 50% less board space than other radial packages. Convection cooling is maximized by the planar package configuration which dissipates heat well above board level. Ohmite’s power chip resistors have a 125% higher operating temperature range than competitive prod- uct of similar design. High temperature solder and in-process plating keep terminations secure under self-heating effects by preventing re-flow from full power operation. Flexible packaging schemes make these resistors ideal for power supplies, audio amplifiers, video fly- back, and other power control applications.
