Chassis Mount Resistors

As one of the most widely used components in the electronic industry, a chassis mount resistor is an electronic device that uses resistance to reduce currents and modify signal levels. An example of a chassis mount resistor is TE50B120RJ, which can be used for various purposes due to its compact and robust design. This article will discuss the application field and working principle of TE50B120RJ.

Application Field

TE50B120RJ is a two-terminal thin-film resistor, which can be used in a wide range of applications. It is mainly used in audio and power electronics for overvoltage protection and voltage control. It can also be used as a power resistor in circuits to limit inrush current, regulate energy dissipation, or act as a current sensor. Due to its reliable and consistent performance, it is also used in high-frequency switching feedback applications and harmonic filtering systems.

Working Principle

The TE50B120RJ uses a metal-oxide thin-film technology to achieve its impressive resistance level. This thin-film technology is based on building multiple layers of very thin metal oxide films on the resistor substrate which serve as a kind of resistance material. These thin-film layers are applied in parallel or in series in order to create the desired resistance values and other parameters. The total resistance of the resistor is then determined by the total number of layers, the materials used in the thin-film and the thickness of each layer.

In addition, the resistor’s resistance value can be further controlled by applying a voltage to its terminals. This is done by passing a small current through the resistor and measuring the voltage drop across it. This process is known as voltage regulation, and it allows engineers to adjust the resistance value of the resistor with a high level of accuracy and repeatability.

Finally, the TE50B120RJ is designed for high-frequency operations and ensures a very low noise level. Its wide temperature range and high insulation voltage make it suitable for use in harsh environments. Additionally, the resistor features a thermal overload protection which safely limits the current in the event of an unexpected overheating.

Conclusion

The TE50B120RJ is a versatile chassis mount resistor which is suitable for a wide range of applications. It has a reliable and consistent performance and provides a high degree of accuracy and repeatability. Its high-frequency operation and thermal protection further enhance its robust design, making it suitable for even the most demanding applications.
