Chassis Mount Resistors: F40J200E Application Field and Working Principle

Chassis mount resistors are a type of electrical component used in many industries, such as automotive and aerospace, and are commonly used as voltage regulators, current limiters, and protection circuit components. F40J200E is the most common type of chassis mount resistor, which is designed to offer superior performance and reliability, especially in harsh operating environments. This article will discuss the application field of F40J200E, as well as its working principle.

Application Field

F40J200E resistors are most commonly used in motor traction and military applications. The resistor is designed for exceptional reliability and high thermal stability in these harsh settings, and features a coated resistor element and a corrosion resistant terminal block. The resistor can also be used in cold, high salt, and other corrosive environments. It is also used in marine vessels, oil platforms, and other harsh outdoor locations.

Working Principle

F40J200E resistors consist of a resistive element made of an alloy of 50-52% nickel and 48-50% iron, making it highly corrosion resistant and strong against high temperatures. The high strength of the resistive element means that it can takes high current loads of up to a peak value of 200A without sacrificing performance, making it a good choice for high-current applications such as motor traction. The resistor also features a one-piece ceramic body and a stainless steel terminal block, which helps to protect it against external mechanical and electrical forces. The stainless steel terminal block also ensures that the resistor is resistant to water or moisture entering the case, which can cause corrosion and other problems. Furthermore, the F40J200E is designed to be insulated from its mounting surface, which helps to reduce the risk of short circuits and thermal runaway. Additionally, a heavy-duty aluminum casing helps to protect the resistor from UV radiation, salt spray, and other harsh environmental conditions.

Conclusion

In conclusion, F40J200E is a robust and reliable chassis mount resistor that can be used in a range of industrial applications, such as motor traction and military. Its corrosion-resistant resistance element, stainless steel terminal block, and insulation from its mounting surface help to ensure superior performance and reliability in harsh environments.
