What Is A Chassis Mount Resistor, And What Does It Do?

If you’re an electrician, you might be looking at a circuit board and not know what these little components are called. A chassis mount resistor is one of the most important pieces in the construction of electronic devices. I’ll tell you more about them, and explain why they’re so important!

What Is A Chassis Mount Resistor?

A chassis mount resistor (often abbreviated CMOS or chip-on-board) is a type of resistor mounted on a computer’s motherboard instead of being mounted in the circuit board. This resistor is used to reduce the voltage drop across it and protect electronic equipment from electrical noise. Therefore, this type of resistor is often used when there is a higher power draw from the load than from the power supply, or when there is a risk of damage to the power supply if too much current flows through it.

Uses of a Chassis Mount Resistor

There are many other uses for a chassis mount resistor, including in audio equipment and computer systems. In audio equipment, it is used to reduce the amount of power that is needed to drive an amplifier or speaker. This is done by reducing the amount of current that flows through the speaker. In computer systems, a chassis mount resistor is used to reduce the amount of heat that is produced by the processor.
