Chassis Mount Resistors: 805F50RE Application Field and Working Principle

Chassis mount resistors are an essential component of many electrical systems. They not only provide electrical resistance to a circuit, but also provide structural stability and thermal management. 805F50RE is a composite type of chassis mount resistor. It is a two-piece assembly commonly found in both military and commercial aircraft, helicopters and ground vehicles. This resilient component provides excellent performance in high current and voltage environments. In this article, the application fields and working principles of the 805F50RE will be discussed.

Application Fields of 805F50RE

The 805F50RE chassis mount resistor is primarily used in military applications where maximum power dissipation, stresses to the resistor, and vibration are expected. Its two-piece construction is approved for use in aircraft, missiles, and other military hardware. It is typically certified for up to 950°F/510°C due to its ceramic and brass construction. These electrical components are excellent for high temperature, high vibration, and high current applications, making it the preferred choice for high-performance systems and equipment. The 805F50RE is also popular in commercial applications including industrial machines, motors, pumps, generators, and other power equipment. Its flexibility allows it to be mounted on a wide variety of chassis and wiring configurations with various mounting interfaces. This versatility makes it ideal for retrofit projects and small-scale production runs.

Working Principle of 805F50RE

The 805F50RE functions as an electrical current limiting device in an electrical circuit. These resistors convert electrical energy into heat. Electrons passing through the resistor collide with atoms from its construction, creating energy in the form of heat. This heat is either dissipated into the environment or transferred to a heatsink depending on the application. The 805F50RE is designed to withstand high current and voltage. The two-piece configuration allows it to operate with less stress and less heat accumulation while still handling high current loads. The ceramic core acts as an insulator for the resistive element while also acting as a heat sink to dissipate thermal energy into the environment. The brass body of the resistor is designed to withstand high vibration, enabling it to be used in tough environmental conditions.In conclusion, the 805F50RE is a durable and versatile chassis mount resistor that is suitable for a wide range of applications. Its composite construction and two-piece design provide excellent performance in high current and voltage, high temperature, and high vibration environments. As an electrical current limiting device, it is designed to dissipate heat safely and efficiently while providing protection in risky applications.
