Chassis Mount Resistors are used in industrial, military and space applications where excellent resistance against shock and vibration, corrosion and mechanical robustness is required. The 850F3K0E series of resistors is specifically designed to meet and exceed these performance requirements. In this article, we will discuss the application field and working principle of 850F3K0E resistors.

850F3K0E resistors are primarily designed for applications in high current, high voltage and ultra-high temperature environments, such as: high power rectifiers, inverters, voltage and current regulators, motor drives and generators. The resistors have a wide range of temperature coefficients, from very low to high values, allowing for excellent stability across a wide range of temperatures. They also feature high reliability, high accuracy and very low self-heating characteristics. Due to their outstanding features, 850F3K0E resistors are suitable for use in a variety of applications, making them an ideal choice for designers looking for excellent performance and long life.

The working principle of the 850F3K0E resistor is based on the physical property of resistivity, which is the measure of the resistance of a material to the flow of electric current. The resistance of a resistor is determined by the type of material it is made from and its cross-sectional area. In the case of the 850F3K0E resistors, they are made from materials that are highly resistive, and they typically have a large cross-sectional area. This combination allows for a very high resistance value, even at high currents and high voltage.

The 850F3K0E resistors also feature a unique exhaust stack design, which helps to improve the stability of the resistors in high temperature environments. This design also enhances the performance of the resistor in high vibration applications, ensuring better reliability and extended life. The use of a multi-level platinum wrap construction further enhances the thermal characteristics of the resistor, allowing it to dissipate heat more efficiently and remain cool even under extreme conditions.

The 850F3K0E resistor can be further customized to meet specific requirements. It can be selected to meet the exact resistance value and power rating needed for the application. It can also be fitted with various types of protection, including a thermal protection switch, which is suitable for high temperature applications. The resistor can also be designed to allow for over-voltage and over-current protection, which helps to improve the overall safety of the system.

In summary, the 850F3K0E series of resistors is a versatile product that offers excellent performance and reliability. It is suitable for use in a variety of industrial, military and space applications, with its unique exhaust stack design and wide range of temperature coefficients, allowing all designers to develop reliable systems that can withstand extreme temperatures. This versatile resistor is also customizable, offering excellent performance and long life in high current, high voltage and ultra-high temperature conditions.
