Chassis mount resistors, such as RER75FR909RC02, are used to control electrical current, voltage, and power in a circuit. The main function of these resistors is to reduce overall system power loss by converting some of the input energy into non-usable heat energy. These resistors are typically used in automotive, industrial, and consumer electronics applications. This type of resistor has the advantage of being able to be mounted directly to the chassis of a system or appliance rather than being placed inside the enclosure like most other resistors.
The RER75FR909RC02 consists of a rigid substrate material such as aluminum mounted with two metal plates, which are joined by a thin film resistor element or a thick film resistor element. The metal plates are usually made of copper and feature an insulation layer which helps prevent any dangerous electric shocks or short circuits.The resistor element is designed to be able to withstand wide temperature ranges and is also capable of handling high currents.
The working principle of chassis mount resistors is simple. When current flows through the resistor, due to the resistance created between the two metal plates, some of the electrical energy is converted into heat. This heat is then dissipated through the substrate material, resulting in a decrease in overall system power loss. Additionally, the resistor also serves to protect the connected circuit from excessive current.
Chassis mount resistors are widely used in the automotive and industrial industries as they can operate at high temperatures and can easily be mounted to a chassis. In automotive applications, such as cruise control systems and emission control systems, the resistor helps maintain a stable voltage and current level as well as reduce any unwanted noise. In industrial applications, they are used to regulate voltage and current levels of motors, as well as for temperature and power regulation in production systems and other electrical equipment. In consumer electronics, they are mainly used to reduce noise and provide a stable power supply.
Overall, the RER75FR909RC02 is a popular choice for many applications due to its ability to handle high-currents and its ability to withstand wide temperature ranges. As it is easy to mount directly to a chassis, it is frequently used in automotive, industrial, and consumer electronics applications.
