H81K0DZA

Through Hole Resistors are electronic components that are used to provide resistance to electrical circuits. The H81K0DZA is a horizantal mount resistor that is used for resistive sensing in printed circuit board (PCB) applications. It is a discrete device, with a resistance value between 5 ohms and 1 megaohm (KΩ).

Application Field of H81K0DZA

H81K0DZA is used to provide resistance in almost any application that requires a resistive element, such as analog and digital devices. It is primarily used in industrial applications such as:

• Automotive control systems, such as engine controllers, brake controllers and power control units.
• Safety systems, including airbags, ABS and traction control.
• Power supply and energy storage solutions.
• Data logging and monitoring systems.
• Measuring instrumentation.

Working Principle

The H81K0DZA is made with a metal oxide film that is printed onto the surface of an insulating substrate, such as a glass-reinforced epoxy. This substrate is then sandwiched between two metal electrodes, usually made of nickel or chromium-plated copper. The resistive element is then connected to the electrodes, creating a two-terminal resistor. The resistive element acts as a barrier to the flow of electrical current, resulting in a voltage drop across the terminals. The amount of resistance is determined by the geometry of the substrate and the thickness of the oxide film.

The H81K0DZA is a robust, reliable resistor that can be used in high temperature and high frequency applications. It has a high breakdown voltage and can withstand voltages up to 400V. It also has a high temperature stability up to 125°C, making it suitable for use in harsh industrial environments. The resistor is usually paired with an appropriate PCB for maximum performance.

Conclusion

The H81K0DZA is a through hole resistor that is versatile and reliable. It is suitable for any application requiring resistance, from automotive and safety systems to power supplies and data logging. It has a high breakdown voltage, high temperature stability and can withstand voltages up to 400V. It is a cost effective, easy to use resistor that is well suited for industrial applications.
