The PWR221T-30-10R0F is a TO-220 style power resistor designed for current limiting, capacitor discharge, or current measurement circuits. It provides a resistance of 10 Ω with a precision tolerance of ±1% and a power rating of 30 W at a 25 °C case temperature. Constructed with thick film on an alumina ceramic substrate, this resistor features low inductance, a Temperature Coefficient of Resistance (TCR) of ±100 PPM/°C, and operates over a temperature range of -55 °C to +150 °C. As an AEC-Q200 compliant component, it is well-suited for demanding applications including power supplies, motor drives, rectifiers, and test and measurement equipment.
