Chassis Mount Resistors

Resistors are an important component in many electrical systems, and chassis mount resistors are among the most popular. The type of resistor depends on its application field and working principle; in this case, we\'re focusing on the 825FR70E chassis mount resistor.

Application field

The 825FR70E Chassis Mount Resistor is primarily used in audio, power, telecommunications, and engineering systems. These resistors are an ideal choice for these applications because they are specifically designed to perform reliably and repeatability in high temperature and high power environments.

Construction

The 825FR70E Chassis Mount Resistor is built with a metal case enclosed in an epoxy coating which reduces the stray magnetic fields generated by the resistor. It also features a metalized film resistor design. This improves the temperature stability of the resistor, allowing it to remain accurate and consistent even in hot conditions.

Design Features

The 825FR70E Chassis Mount Resistor has several design features that make it an ideal component for high-power, high-temperature applications. The metalized film construction improves its performance under heat, and its epoxy coating also helps protect the device from dust, oxidation, and other environmental factors. In addition, the 825FR70E includes a quick-connect feature that makes it easy to install in a chassis mounting. This feature eliminates the need for soldering the resistor directly onto the chassis, allowing for a quick and easy installation process.

Working Principle

The 825FR70E is a type of variable resistor that functions by providing resistance to the flow of electrical current. It is constructed with a metal case sealed in an epoxy coating which creates a protective barrier around the conductor. The core of the resistor is made up of a highly resistive track of metalized film which changes its resistance when current passes through it. This change of resistance produces a voltage drop across the resistor, which can be used to regulate the current in an electronic circuit.

Conclusion

The 825FR70E chassis mount resistor is a reliable and versatile component that is well-suited for a variety of applications, including power, audio, telecommunications, and engineering systems. It is constructed with a metalized film resistor design for improved temperature stability and a quick-connect feature to allow for easy installation. The 825FR70E works by providing resistance to the flow of electrical current, which can be used to regulate the current in an electronic circuit.
