Chassis mount resistors are widely used in modern electrical systems. They can be used in a variety of applications, from industrial to consumer, and are generally versatile components. The RER45F12R7RC02 is a type of chassis mount resistor and it has specific applications and a unique working principle.

Application Field

Since this type of resistor is a chassis mounted device, it is ideal for applications where the device must be connected to a chassis or any other grounded surface. This makes it suitable for environments where vibration and environmental conditions have to be considered. It is commonly used in automotive applications that require a stable reference point built into the system.

This component is also well-suited for power electronics due to its high-capacity conductors and air-filled insulation. This makes it suitable for higher ambient temperatures, up to 85°C, which is common for many power electronics systems.

Working Principle

The RER45F12R7RC02 is a low-power chassis mount resistor specifically designed for use in applications that require high reliability and accuracy. The most common construction consists of two insulated conductors formed into a cylindrical shape and filled with air. The two conductors are made of different materials; one of the conductors is made of a highly resistive material such as carbon or manganese, while the other is made of a less resistive material such as copper or nickel.

The main idea behind this construction is that when the two conductors come into contact with each other, the current flowing between them will create an electromotive force (EMF) causing a resistive effect due to the difference in the resistivities of the two materials and the distance between them. This resistive effect is what is used to produce the desired resistance in the system.

The RER45F12R7RC02 also utilizes an insulation layer around the two conductors to reduce electrical leakage and improve resistance accuracy. This layer of insulation helps ensure that the resistance values remain constant within acceptable limits.

Overall, the RER45F12R7RC02 can be used in a variety of industrial and consumer electronics applications, such as automotive, power supplies, instrumentation, and consumer electronics. It is a reliable and versatile component and its unique working principles make it suitable for many applications.
