Through Hole Resistors—as integral components in modern-day electronics—are affordably priced and remarkably versatile, making them an ideal option for projects ranging from simple circuitry to the most complex designs. The H812K4BYA series, in particular, is a reliable basic size leaded resistor that offers users up to 9W of continuous power dissipation with a tolerance of ±2%.

Designed for a wide range of applications, the H812K4BYA are surface mountable thick film resistor chip inductors featuring an aluminum oxide passivation. This passivation helps reduce the effects of temperature cycling, enhances transient response characteristics, and besides affording long term stability over a wide temperature range also extends the life of the resistor.

H812K4BYA series are especially well-suited to applications such as computing, communication, automotive, and consumer electronics markets. Notable features include:

• Temperature Coefficient (TCR): ±50PPM/°C
• Operating Temperature Range: -55°C to +125°C
• Rated Power: 9W
• Insulation Voltage: 500V

With regard to its operating principle, the H812K4BYA performs by generating a voltage drop across its terminals when current passes through it. The magnitude of the voltage drop is proportional to the resistor\'s resistance, however, there will be some degree of heat dissipation in the process. This is why it\'s important to select a resistor that provides enough power to handle the heat generated by the current. Resistance values of the H812K4BYA range from 0.1Ω–100KΩ.

H812K4BYA offer a few other benefits as well. These include their small size, which allows for a minimal amount of board space as well as excellent size stability with minimal tolerances. Furthermore, they have excellent stability over temperature, which helps to maintain a constant resistance over a wide range of temperatures. Another useful feature is the inductive nature of thick film resistors, which allows for a reduction in lead inductance, compared to metal film or carbon resistors.

To conclude, the H812K4BYA is a reliable and capable component with several advantages over other resistors. With its wide operating temperature range and resistance values, it can fit a wide range of projects from basic circuitry to more complex designs. Consumers seeking features such as size stability, low inductance, and excellent stability over temperature should certainly consider these resistors as a viable option.
