RNP20S TO220 35W HIGH POWER RESISTORS POWER SOLUTIONS – WILLOW TECHNOLOGIES LTD Features and Applications 35W high power resistors in TO220 style mold package for through-hole and surface mount. Non-inductive design suits high frequency applications and high-speed pulse circuits. Low, 3.3 deg C/W heat resistance from resistor hot spot to flange and long life performance are presented with thin film metallization technology and rejection of plastic adhesive joint. Wide 100 milliohm to 51kOhm resistance range, non-inductive impedance characteristic and heat conduction through the insulated metal flange aid circuit designers. Small size and thin profile suit high-density compact installations. Complete thermal conduction, heat dissipation design and vibration durable design also available. Applications for UPS, power unit of machines, motor control, drive circuits, automotive, measurements, industrial computers and high frequency electronics.
