TTM-52M220
Power Resistors are available in a compact TO-220 package with a thick film on
ceramic technology that provides the advantage of 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 0.5%,
1% and 5% tolerance options. These TTM-52M220 resistors are ideal for use in
current limiting, capacitor-discharge, or current measurement circuits in power
supplies for telecom and industrial applications.
