Through hole resistors are a common type of electrical component used for controlling current flow in a circuit. The resistance of a resistor determines how much current is allowed to flow when an electrical voltage is applied to it. The H81K69BCA is a type of through hole resistor that has a lot of advantages over other types. This article will discuss the application field and working principle of the H81K69BCA.

Application Field of H81K69BCA

H81K69BCA is mainly used in military communication and aerospace industry. The H81K69BCA series is specifically designed for precise current-limiting applications. It’s most suited for power supplies that require tight regulation and temperature robustness. It also has a high temperature drift rating, making it suitable for operation in extreme temperatures. The H81K69BCA series can be used to precisely limit current in switching power supplies, DC servos and other applications.

Working Principle

The H81K69BCA resistor works by limiting the amount of electrical current that flows through a circuit. The resistor acts as a resistance to the current, dissipating energy in the form of heat. The resistance is determined by the size and material of the resistor, and the voltage across the resistor will determine how much current passes through it. The H81K69BCA resistor uses ceramic high-stress layers that are impregnated with a metal oxide film. This creates a low-resistance path between the metal layers.

The ceramic layer also gives the resistor the ability to quickly dissipate heat, which allows it to withstand high temperatures. The metal oxide film also acts to buffer the temperature of the resistor, preventing it from overheating. The H81K69BCA series is available in a variety of sizes and wattages, allowing it to be used in a wide range of applications.

Conclusion

The H81K69BCA is a type of through hole resistor that offers a lot of advantages over other types. It is mainly used in military communication and aerospace industry, and can be used in a wide range of applications. The H81K69BCA resistor works by limiting the amount of electrical current that flows through a circuit, using a ceramic high-stress layer and a metal oxide film to create a low-resistance path.
