This article will discuss the H81K91BCA application field and working principle in detail.

Application Field

The H81K91BCA through hole resistor is widely used in many consumer and industrial application areas. It is used in various applications to provide electrical power control, regulation, distribution, and protection. This type of resistor is suitable for high voltage, high frequency, and high power applications. It is also used in AC/DC power converter circuits, motor speed control circuits, and motor control circuits. Additionally, the H81K91BCA can be used in medical equipment, telecommunications equipment, automotive electronics, and other consumer electronics.

Working Principle

The H81K91BCA through hole resistor is an active-type resistor, meaning that it uses an active feedback circuit to maintain a stable resistance value. The active feedback circuit consists of three elements: the power supply, the load, and the gate resistor. When electricity passes through the reference resistor, the gate resistor controls the voltage drop across the load, maintaining a constant and stable resistance value. The resistor will then supply the required current to the load, thereby controlling the amount of power delivered to the load.

The H81K91BCA is constructed with a metal oxide film, which is made from layers of aluminum, zinc, and an oxide insulating layer. This construction ensures a stable resistance value even at high temperatures. The metal oxide film also helps increase the breakdown voltage of the resistor, enhancing its overall durability. Furthermore, the H81K91BCA is heat-resistant and has excellent mechanical strength and environmental resistance.

Conclusion

In conclusion, the H81K91BCA through hole resistor is a versatile and reliable type of resistor. It is designed for many industrial and consumer applications and can provide stable, reliable power control, regulation, distribution, and protection. The metal oxide film construction ensures a stable resistance value even at high temperatures, and the resistor is heat-resistant and has excellent mechanical strength and environmental resistance. The H81K91BCA is an ideal choice for many types of applications that require reliable power control and regulation.
