Chassis Mount Resistors

A chassis mount resistor is an electrical device used to reduce the flow of electricity in a circuit, lowering the current. Chassis mount resistors are commonly used to regulate the voltage in electrical circuitry, as well as protect other components from damage due to unintended overloads. One example of a chassis mount resistor is the RER40F[2670RC02](http://www.tt-electronics.com/resistors-fixed-single-layer/rer40f-2670rc02.html).

RER40F2670RC02 Application Field and Working Principle
