Through Hole Resistors are vital components found in a wide range of electronic applications; the H81K0BBA is one such example of these. On closer inspection, the H81K0BBA contains a number of unique features that make it suitable for certain applications and not for others. In this article, we will take an in-depth look at the application field and working principle of the H81K0BBA.

Applications of the H81K0BBA

Firstly, let’s take a look at the various applications of the H81K0BBA through hole resistor. Depending on its intended application, the H81K0BBA has a working power rating of up to 250W. This makes it suitable for applications in the automotive, lighting, industrial, audio/visual and telecom sectors. Its operating temperature can range from -50°C to +175°C, making it useful for these extreme temperature applications.

The H81K0BBA is also ideal for use in switching supplies. This is because it has a fast response time and an operating voltage of up to 25V. Additionally, the resistor has a low Inductance noise coefficient, making it suitable for use in noisy environments. These features make it ideal for use in audio broadcasting and other audio/visual applications.

Another strength of the H81K0BBA through hole resistor is its high precision and stability. This is due to its precision molded and plated contact that gives it a tolerance of less than 1%. Additionally, the resistor has a low temperature coefficient of resistance, ensuring its accuracy over time, even if the surrounding temperature changes. This makes it ideal for use in both high-precision and low-power applications.

Working Principles of the H81K0BBA

The H81K0BBA employs a ceramic material as its substrate or body, with a metalized film deposited over it. This provides the resistor with its high precision and stability. It also adds to the operating temperature range of the device, allowing it to operate in higher temperatures than standard film resistors.

The resistor is then wound with a helical coil, that is encased in a small cylindrical casing. This casing is then filled with a protective epoxy resin, to ensure the coil is securely shielded from the outside environment. With this construction, the H81K0BBA is able to maintain its tolerance and accuracy over its operating life.

The H81K0BBA also features an internal resistor mounted on a printed circuit board (PCB). This internal resistor helps to increase the overall accuracy and stability of the device. The PCB also provides an additional layer of protection, ensuring the device is even more secure from outside environmental factors.

Conclusion

In summary, the H81K0BBA is an ideal through hole resistor for a wide range of applications. It is well suited for both low-power and high-precision applications. Its suitability for audio/visual applications is highlighted by its low inductance noise coefficient and fast response time. It is also well suited for use in extreme temperature applications due to its operating temperature range. Additionally, its internal resistor mounted on a PCB provides an additional layer of protection and accuracy.
