PWR220T-20-25R0F is a TO-220 DPAK style power resistor manufactured by Bourns using thick film on alumina ceramic technology. This 20 W resistor features a resistance value of 25 O with ±1% tolerance, low inductance of 0.1 µH maximum, and electrical isolation from the backplate. The device operates over a temperature range of -55°C to 155°C with a thermal resistance of 6.5°C/W and a temperature coefficient of resistance of ±100 PPM/°C. It is AEC-Q200 qualified and RoHS compliant, making it suitable for power supplies, motor drives, test and measurement equipment, and rectifier circuits where reliable current measurement and snubber functionality are required.
