PWR263S-35-3R00F is a 35 W power resistor manufactured by Bourns using thick-film technology on alumina ceramic substrate, housed in a D²PAK (TO263) surface-mount package. The device features a resistance value of 3 O with ±1% tolerance, low inductance of 0.1 µH maximum, and thermal resistance of 3.7 °C/W, enabling efficient heat dissipation in demanding applications. Operating across a temperature range of -55 °C to 155 °C with a maximum operating voltage of 250 V, the resistor is electrically isolated from the backplate and compatible with lead-free solder reflow processes. This component is ideal for power supplies, motor drives, rectifiers, and test equipment where reliable current measurement, snubber, bleeder, and discharge circuit functionality is required, with AEC-Q200 qualification and RoHS compliance ensuring automotive and industrial reliability.
