Chassis Mount Resistors

Chassis mount resistors, sometimes referred to as panel mount resistors, are devices designed to be mounted to a metal chassis. They are specifically designed to dissipate heat and provide a stable electrical path for the electrical current. In some cases, they may also be used as part of a circuit board or in other applications requiring resistors with high strength, temperature stability, and low cost.
