PWR220T-20-3300F is a TO-220 DPAK style power resistor manufactured by Bourns using thick film on alumina ceramic technology. This 20 W rated resistor features a resistance value of 330 O with ±1% tolerance, low inductance of 0.1 µH maximum, and thermal resistance of 6.5 °C/W. The device operates over a temperature range of -55°C to +155°C with a temperature coefficient of resistance (TCR) of ±100 PPM/°C, and is electrically isolated from the backplate for enhanced safety. The resistor 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, snubber, bleeder, and discharge functions are required.
