PWR221T-50 Power Resistors

Bourns PWR221T-50 Power Resistors are available in a compact TO-220 package with a thick film on ceramic technology that provides low inductance. These power resistors are through-hole, radial leaded resistors with a wide resistance value range from 20mΩ to 130KΩ. The radial leaded resistors are available in 1% and 5% tolerance options. Bourns PWR221T-50 resistors are ideal for current limiting, capacitor discharge, or current measurement circuits in power supplies for telecom and industrial applications.
