PWR163S-25-1R50J is a 25 W DPAK-style surface mount power resistor from Bourns with a resistance value of 1.5 O and ±5% tolerance. The device features very low inductance (0.1 µH maximum) and excellent thermal characteristics with a thermal resistance of 5.2 °C/W, making it ideal for high-frequency applications such as amplifiers and wireless base stations. It operates over a temperature range of -55°C to 155°C with a temperature coefficient of ±100 PPM/°C, and supports an operating voltage up to 250 V. The resistor is electrically isolated from the backplate, RoHS compliant, and AEC-Q200 qualified, with excellent pulse characteristics suitable for current limiting and capacitor discharge circuits. Common applications include power supplies, motor drives, test and measurement equipment, and rectifiers.
