Through Hole Resistors (THRs) are widely used in the industry and are durable components that provide both reliable connections and beneficial features. The H81K43BDA is one of the most popular types of THRs available today. This article will explore the application field and working principle of the H81K43BDA.

Overview of the H81K43BDA

The H81K43BDA is a three-terminal Through Hole Resistor. It features a permanent connection between its anode and cathode, allowing for stable current flow regardless of any environmental influences. Its terminals are designed to be easily attached to a printed circuit board, providing convenient installation and maintenance. Its cathode also has a built-in positive temperature coefficient (PTC), allowing it to automatically adjust its operating current when exposed to high temperature. Features like these make the H81K43BDA a powerful and reliable THR.

Application Field of the H81K43BDA

The H81K43BDA is the perfect choice for applications requiring high-temperature operation. Its PTC feature allows it to automatically adjust its operating current when exposed to high temperature, making it the ideal THR for servers, telecommunications equipment, and a variety of automotive applications. In addition, it is designed to provide reliable current flow in the most challenging environments.

The H81K43BDA is also an excellent choice for applications requiring a large operating voltage range, making it suitable for powering audio devices and safety systems. The device\'s terminals are designed to be easily attached to a printed circuit board, ensuring efficient installation and maintenance.

Working Principle of the H81K43BDA

The H81K43BDA is a three-terminal THR that uses two diodes in series to provide a constant voltage operation. The device uses a Schottky barrier diode (SBD) and a series reverse-biased n-type diode (RD) connected in series between the anode and cathode. The SBD provides a voltage drop that acts to prevent current leakage from the anode to the cathode. The RD provides additional current conduction to help establish a stable operating voltage range. The device also contains an internal PTC that automatically adjusts its operating current when exposed to high temperature.

The H81K43BDA also features a permanent connection between its anode and cathode, allowing for stable current flow regardless of any environmental influences. This connection ensures that the device will be able to remain operational for extended periods of time, even in extremely challenging conditions.

Conclusion

The H81K43BDA is a three-terminal THR that provides a permanent connection between its anode and cathode. Its features include a built-in positive temperature coefficient (PTC) and a large operating voltage range, making it the ideal THR for a variety of high-temperature, high-voltage applications. Additionally, its terminals are designed to be easily attached to a printed circuit board, ensuring efficient installation and maintenance. In summary, the H81K43BDA is an ideal choice for applications requiring reliable connections and beneficial features.
