The PWR221T-30-50R0F is a thick film power resistor in a TO-220 package, designed for current limiting, capacitor discharge, or current measurement circuits. This through-hole component provides a resistance of 50 Ω with a tight tolerance of ±1% and a power rating of 30 W at 25°C case temperature. Constructed with thick film on an alumina ceramic substrate, it features low inductance, a ceramic backplane, and is AEC-Q200 compliant. Its robust design makes it ideal for demanding applications such as power supplies, motor drives, and test and measurement equipment where high power dissipation and reliability are critical.
