One of the most versatile through hole resistors is the UB5C-43R1F8. It is designed to deliver both high accuracy, power handling, and long-term stability, making it an ideal choice for a variety of industrial applications. The focus of this article is to explain the application fields and working principles of this resistor.

Application Fields

The UB5C-43R1F8 is a special type of through hole resistor. It is designed to meet specific requirements, such as operating higher temperatures, long-term stability, and high power handling. This resistor is mainly used in industrial applications, such as medical devices, data centers, power electronics, communication and telecom, and automotive components. In these applications, the UB5C-43R1F8 is usually used as a voltage or current limiter, frequency regulation, reliability increase, and safety assurance.

Working Principle

The UB5C-43R1F8 contains two metal films with a controlled amount of tungsten. When the resistor is energized, the tungsten ions move across the films. This movement forms an electrical resistance between the two films. As the current flows through the resistor, a voltage drop is created, which is proportional to the amount of current. The voltage drop then stabilizes, resulting in a fixed amount of power. This power is regulated by a combination of the resistor’s resistor value, and the bias voltage.

When the voltage is applied to the resistor, it is controlled by the bias voltage. This voltage is used to control the power dissipation across the resistor. If the power is too high, the resistor will become thermally overloaded and the resistor will fail. The bias voltage is used to reduce the power dissipation and therefore, prevent the resistor from failing.

The UB5C-43R1F8 is also able to handle large currents because of its wide current-handling capabilities. This resistor is designed to dissipate high levels of power without creating thermal runaway. It also has a low temperature coefficient, making it ideal for applications involving temperature cycling. Finally, this resistor is designed to have minimal signal distortion, ensuring accurate readings and reliable performance.
