Chassis Mount Resistors

Chassis mount resistors are robust components designed to handle high power and are commonly used in industrial and automotive applications. These resistors are mounted directly onto a chassis to dissipate heat more efficiently, making them ideal for situations where high levels of reliability and endurance are required.

Why Use Chassis Mount Resistors

Chassis mount resistors, particularly wirewound chassis mount resistors, feature a design where metallic wire is wound around a core of non-conductive material, encased in a metal (usually aluminium) housing for enhanced heat conduction.

Where Would You Use a Chassis Mount Resistor

Chassis mount resistors are commonly used for large electrical and production machinery, motor start or stop cycles, equipment discharge, load test simulation and dynamic braking.

Chassis mount resistors are also particularly suited for applications where the resistor is used to promote heat loss and cooling, because of its low temperature coefficient of resistance (TCR) – in other words, its resistance remains nearly constant over a wide range of temperatures.
