Chassis Mount Resistors

Resistors are some of the most commonly used components in electronic circuits and often one of the first components a student learns about in any electronics course. Chassis mount resistors are resistors that are mounted to a chassis or housed in a package and use the chassis or package for heat dissipation.

Application Field

RER40F2210RC02 is a high power and low resistance chassis mount resistor. It is usually used in power supplies, amplifiers, voltage regulators, and other high-power electronic circuits. It is also used in regenerative braking systems and electronic parking systems.

Working Principle

When an electrical current is applied to the resistor, a voltage is created across the resistor. This voltage is determined by the value of the resistor and the current in the circuit. In chassis mount resistors the electrical current is dissipated as heat in the heatsink or chassis. The heat is dissipated into the chassis or atmosphere and maintains the temperature at an acceptable level to prevent damage to the circuitry.

Chassis mount resistors are typically composed of metal with a non-conductive insulation material around it which prevents shorts in the circuit. The metal is typically made from either copper or Aluminium while the insulation can be composed of ceramic, glass-fiber, polyamide, polyimide, or ceramic-metal composites depending on the desired application.

RER40F2210RC02 is a high power chassis mounted resistor designed to work in a wide range of operating temperatures from -55 to +125 degrees Celsius. It also has an impressive power rating of up to 125 Watts and an incredibly low resistance of 0.01 ohms, making it suitable for high current applications.

Although operating in entirely different environments, the basic working principle of RER40F2210RC02 does not differ much from that of other chassis mount resistors. The resistance of the resistor affects the amount of current which is allowed to flow, and the heatsink or chassis is used to dissipate the heat generated by the current, keeping the temperature of the device at an acceptable level and preventing it from becoming damaged.
