Bourns PWR221T305R00J TO-220 Power Resistor
Bourns PWR221T-30 series power resistors are designed for demanding applications requiring high power dissipation and reliability. These resistors, housed in a TO-220 package, employ thick film on alumina ceramic technology, providing excellent thermal performance and stability. They are commonly used in power supplies for telecom and industrial applications, as well as in motor drives and test and measurement equipment. The AEC-Q200 compliance ensures suitability for automotive applications, while RoHS compliance meets environmental standards. Available in a wide range of resistance values and tolerances, the PWR221T-30 series offers a versatile solution for current limiting, capacitor discharge, and current measurement circuits.
