Chassis Mount Resistors are a type of resistors used to dissipate electrical energy from a circuit and to reduce the amount of current flowing through a circuit. The most common type of Chassis Mount Resistors are RSA-50-100.

An RSA-50-100 resistor is a wire wound type of resistor, with an operating temperature rating of 100 ˚C. This type of resistor has three main features: firstly, it provides a comparatively high resistance with low dissipation; secondly, it is made with an open construction to allow maximum airflow; and thirdly, the insulation used in its construction reduces the risk of arcing.

RSA-50-100 resistors have several applications in the field. They can be used as voltage dividers in circuit design, protecting current-limiting devices from over-current and short circuit events, and providing current stabilization. In the automotive industry, RSA-50-100 resistors are used as heat sinks for alternators and starter motors, and to provide balance to injectors and carburetors. They are also used in the aerospace industry for temperature compensation, and to control the flow of current in engines and starter motors.

The working principle of an RSA-50-100 resistor is relatively simple. It works by passing a given current through an electrically conductive coil made up of resistance wire. This resistance limits the amount of current that can flow through the device, and allows energy to be dissipated from over-current or short-circuited circuits. The open construction of the device allows for maximum air flow around the coils, increasing its efficiency and allowing it to dissipate more energy.

The advantages of RSA-50-100 resistors are that they are cost effective, provide high resistance with low dissipation, and are made from high quality materials. Also, this type of resistor is relatively tolerant to corrosion and dirt, making it suitable for use in difficult environments. Additionally, the insulation used in its construction helps to reduce the risk of arc-flash.

In conclusion, RSA-50-100 resistors are a type of Chassis Mount Resistors used for many applications. They are cost-effective, efficient, and reliable, and provide a high resistance with low dissipation. They are used in a variety of industries, from automotive to aerospace, and are made from high quality materials. Their open construction provides maximum air flow, reducing the risk of arcing and allowing them to dissipate energy more efficiently.
