PWR263S-35-15R0J is a 35 W power resistor manufactured by Bourns using thick film on alumina ceramic technology in a TO263 D²PAK surface-mount package. This resistor features a resistance value of 15 O with ±1% tolerance, low inductance of 0.1 µH maximum, and thermal resistance of 3.7 °C/W, making it suitable for high-power dissipation applications. The device operates over a temperature range of -55 °C to 155 °C with a temperature coefficient of resistance of ±100 PPM/°C, and is rated for a maximum operating voltage of 250 V. It is RoHS compliant and AEC-Q200 qualified, with the resistor electrically isolated from the backplate for enhanced safety. Common applications include power supplies, motor drives, current measurement circuits, snubber networks, and test and measurement equipment where reliable high-power performance is required.
