Bourns PWR221T3010R0J TO-220 Power Resistor
Bourns PWR221T-30 series power resistors are designed for demanding applications requiring high power dissipation and reliability. Constructed using thick film on alumina ceramic technology, these resistors are housed in a TO-220 package and offer a power rating of 30W. They are AEC-Q200 compliant, ensuring suitability for automotive applications, and RoHS compliant. Common applications include power supplies, motor drives, test and measurement equipment, and rectifiers. The resistor's low inductance and high power rating make it ideal for current limiting, capacitor discharge, and current measurement circuits. Users should consult the datasheet for detailed specifications and performance characteristics.
