The Bourns PWR221-2FCR330F is a high-power resistor from the PWR221 F Series, designed for demanding applications. Manufactured using thick film on Alumina ceramic technology, this resistor offers a power rating of 50W with an external heat sink and 1.50W in free air at 70°C.
Key electrical characteristics include a resistance value of 330 mΩ with a tight tolerance of ±1%. The temperature coefficient is ±100 PPM/°C for resistance values between 0.1 Ω and 100.0K Ω. It operates within a wide temperature range of -40°C to 155°C.
This component is housed in a TO-221 package, suitable for through-hole mounting. Its construction provides low inductance and features pulse-withstanding capabilities. The substrate is Alumina (AL203) with a housing made of Epoxy/PPS and tinned copper lead frames.
Applications for the PWR221-2FCR330F include power supplies, motor drives, and measurement equipment where reliable high power dissipation is required.
