The Bourns PWR263S-20-4R70F is a high-power surface-mount resistor from the PWR263S-20 series. It offers a resistance value of 4.7 Ohms with a tight tolerance of ±1% and a power rating of 20W at 25°C case temperature.
This resistor is constructed using thick film on alumina ceramic technology, providing excellent thermal performance with a thermal resistance of 6.5 °C/W. It operates across a wide temperature range of -55°C to 155°C and features low inductance (0.1 µH maximum).
The component is housed in a D2PAK (TO-263-3) package, suitable for reflow soldering processes. Its electrically isolated backplate and robust construction make it ideal for current measurement, snubber, bleeder, and discharge circuits. The PWR263S-20 series is also AEC-Q200 compliant, making it suitable for automotive applications.
Key electrical characteristics include a maximum operating voltage of 250V, dielectric strength of 2 KV AC, and insulation resistance of 10 GΩ. The temperature coefficient is ±100ppm/°C.
