The Bourns PWR163 Series resistor, part number PWR163S-25-3R30F, is a DPAK style surface mount power resistor. It offers a resistance value of 3.3 Ohms with a tight tolerance of ±1% and a high power rating of 25W at 25°C case temperature.
This resistor is designed for demanding applications, featuring low inductance, making it suitable for high-frequency circuits such as audio amplifiers or wireless base stations. It also exhibits excellent pulse characteristics, useful in current limiting or capacitor discharge circuits. The component is electrically isolated from its backplate and is compatible with lead-free solder reflow processes.
Key electrical and thermal characteristics include a TCR of ±100 PPM/°C, a thermal resistance of 5.2 °C/W, and a maximum operating voltage of 250V. The operating temperature range is -55°C to 155°C. The resistor is constructed with a thick film element on an alumina substrate, housed in epoxy, and features tinned copper pins.
Compliance and reliability are addressed with AEC-Q200 and RoHS 3 compliance. It meets stringent requirements for load life, thermal shock, and vibration, with specific resistance change limits under various stress conditions. The package is a DPAK style, suitable for surface mounting.
