Chassis Mount Resistors
The type of chassis mount resistors, the RER70F76R8RC02, is designed to provide dynamic resistance with low inductance. As the name implies, these components are installed and mounted onto a chassis or other metallic base. They are built with high-quality ceramic composition and a thick-film resistive element. The RP75F series is constructed with a layer of gold for added reliability. The top portion of the resistor is usually made of glass, plastic, ceramic, or other materials, and the bottom portion is made of metal. This combination creates a robust and reliable connection that is particularly suited for industrial, military, and aerospace applications.
Application fields
The RER70F76R8RC02 chassis mount resistor is primarily used in industrial, military, and aerospace applications, as well as various other high-performance applications. Common applications include controlling and regulating devices, managing static and dynamic temperature, and providing feedback signals for motor control. In addition, they are designed for use in higher-temperature conditions, such as those expected in engine control systems.
Due to the longevity of the components and their adherence to stringent manufacturing standards, they are often used in telecommunications systems, RF applications, medical equipment, and aerospace and military systems. These components are designed to withstand extreme temperatures and long-term use. As such, they are extremely useful in environments where endurance and repeatability of parameters are essential.
Working Principle
The RER70F76R8RC02 is designed with a thick-film resistive element, which is composed of a mixture of ceramic, glass, and metal. This element was created to provide dynamic resistance and low inductance. The thick-film resistive element is why the device is able to operate at such high temperatures.
When electrical current begins to flow through the device, the ceramic, glass, and metal materials become electrically charged, causing their temperatures to rise and their resistances to increase accordingly. The resistor’s resistance level is determined by the amount of material used on the resistive element. Depending on the design of the device, the resistance level can be adjusted with the addition or removal of electrical current.
