PWR263S-35-1000F is a 35 W power resistor in TO263 D²PAK surface-mount package manufactured by Bourns using thick film on alumina ceramic technology. This specific variant features a resistance value of 100 O with ±1% tolerance and is designed for current measurement, snubber, bleeder, and discharge circuits. The resistor exhibits low inductance (0.1 µH maximum), thermal resistance of 3.7 °C/W, and operates reliably across -55 °C to 155 °C with a temperature coefficient of ±100 PPM/°C. It is RoHS compliant and AEC-Q200 qualified, with dielectric strength rated at 2 kV AC and maximum operating voltage of 250 V. The device is ideal for power supplies, motor drives, test and measurement equipment, and rectifier applications where high power dissipation and precision current sensing are required.
