Chassis Mount Resistors: RER75F2R20RCSL application field and working principle

Chassis mount resistors are one of the most important types of resistors that are used today. They are used in a wide variety of applications from aerospace, defense, medical, automotive and telecom. They are easy to install in most applications and provide an efficient connection solution for low to high power applications.

The RER75F2R20RCSL is an example of a chassis mount resistor manufactured by CTS. This particular component is a pulse/audio rating type resistor. It is designed for applications that require high power pulses or to eliminate hissing noise on audio systems. It has a maximum wattage rating of 75W, a resistance rating of 2 ohms and a maximum voltage rating of 20V.

The RER75F2R20RCSL is constructed using nichrome wire for its resistive elements that is then permanently sealed in ceramic casing. It is available in a choice of printed circuit board mount or wire ended configurations. The component includes a built-in thermal fuse that trips when the temperature of the resistor exceeds a pre-set rating. This helps prevent overheating and damage.

The RER75F2R20RCSL works by providing controlled resistive electrical energy. As a current passes through the resistor, heat is generated and dissipated from the component. The resistor is designed to have a specific amount of resistance for each power or voltage rating. Therefore, the current is held back, reducing the voltage level to a desired value.

The application field of the RER75F2R20RCSL includes automotive, telecom, computer, consumer electronics and industrial control systems. It is especially useful in applications that require high current pulses such as in current transformers or automotive systems. The component is an ideal solution for suppressing hissing noises or high-frequency transients that can cause interference or damage to audio systems.

The RER75F2R20RCSL is an efficient and dependable chassis mount resistor that can be used in a wide range of applications. With its pulse/audio capability, higher power rating and built-in thermal fuse protection, the component can be used with confidence in any application requiring a reliable resistor solution.
