PWR263S-35-20R0FE is a 35 W D2PAK surface-mount power resistor manufactured by Bourns using thick film on alumina ceramic technology. This specific variant features a resistance value of 20 O with ±1% tolerance and is designed for current measurement, snubber, bleeder, and discharge circuits. The resistor exhibits low inductance (0.1 µH maximum), a thermal resistance of 3.7 °C/W, and operates across a temperature range of -55°C to +155°C with a temperature coefficient of resistance of ±100 PPM/°C. It is electrically isolated from the backplate, rated for a maximum operating voltage of 250 V, and features dielectric strength of 2 kV AC and insulation resistance of 10 GO. The device is RoHS and AEC-Q200 compliant, compatible with lead-free solder reflow, and ideal for high-power applications requiring reliable thermal management and low parasitic inductance.
