Through hole resistors are an integral part of electronic circuits, performing a range of important electrical functions. The UB5C-390RF1 is a versatile through hole resistor, featuring a metal-oxide film construction that offers high stability and excellent temperature coefficient. This makes it an ideal choice for use in commercial and industrial applications. In this article, we’ll take a look at the application field and working principle of the UB5C-390RF1.

The UB5C-390RF1 is well suited for use in low power, low voltage circuits, with a rated power of 0.25W, a tolerance of 5%, and a linear temperature coefficient (inversely proportional to load power). Its metal-oxide film construction offers superior stability and resistance to thermal shock and static electricity, making it an excellent choice for temperature-critical circuits.

The UB5C-390RF1 is also well suited for use in precision DC and AC switching circuits, where it can be used to provide precise voltage regulation and protection against current surges. Additionally, it can also be used in amplifiers, microprocessors, and digital circuits, where it can provide the same reliability and precision as a higher-power, higher-voltage device. Finally, the UB5C-390RF1 is also suitable for use in high-frequency RF circuits, where its high linearity and excellent temperature coefficient make it an ideal choice.

The working principle of the UB5C-390RF1 is relatively simple. When current is applied to the board, the resistor absorbs some of the energy, reducing the potential of the circuit. This reduces the current drawn by the circuit, allowing it to function at a much lower voltage than was initially required. By precisely controlling the amount of current drawn, the UB5C-390RF1 can be used to regulate and protect delicate electronic circuitry.

In summary, the UB5C-390RF1 is a versatile through hole resistor, offering high stability and excellent temperature coefficient in commercial and industrial applications. It can be used in a wide variety of electronics circuits, providing precision voltage regulation and protection against current surges. Its simple working principle makes it an ideal choice for DC and AC switching circuits, amplifiers, microprocessors, and digital and RF circuits.
