Through Hole Resistors - H848K7BZA Application Field and Working Principle

Through hole resistors are one of the most common passive components used in circuits, covering a wide range of applications. The H848K7BZA is a type of through-hole resistor that is commonly found in electronic and electrical systems. This article will discuss the H848K7BZA fields of application as well as its working principle.

What is the H848K7BZA?

The H848K7BZA is a surface-mount resistor that is manufactured with Carbon Film technology. It is a 0.25 watt rated resistor with a tolerance of 20 %. The H848K7BZA is a four terminal device with a rated resistance of 750 Ω. This 4-band resistor features a locking tab to secure wire terminations.

Fields of Application

The H848K7BZA is used in a variety of applications where reliability and performance are required. It is commonly used in electronic and electrical systems such as audio amplifiers, industrial controls, oscillators, and input/output peripheral circuits. The H848K7BZA can also be used in automotive applications as part of motor control systems.

This through-hole resistor is also suitable for use in power supplies and low voltage systems. It is popular with hobbyists and engineers as it is an inexpensive component that is easy to install, thanks to its locking tab feature. It is also easily replaced if replacement is needed.

Working Principle

Most through-hole resistors are made from carbon film deposited on ceramic cores. The H848K7BZA is no different. When the resistor is in operation, current passes though the thin carbon film, causing it to heat up. The heat generated is compared against the current, and a resistance value is created. This value is what allows the device to regulate the flow of current.

The heat generated is dissipated to the surrounding environment. This is due to the release of electrons that carry energy away from the resistor. The resistance value of the H848K7BZA ensures that the energy is dissipated in an acceptable way.

It should be noted that the H848K7BZA is also temperature-sensitive. As the temperature changes, the resistance value also changes. This phenomenon is known as "thermal coefficient of resistance". The amount of change can be calculated relative to the ambient temperature.

Conclusion

The H848K7BZA is a type of through-hole resistor that is used in a variety of applications. It is popular with hobbyists and engineers as it is both economical and easy to install. The H848K7BZA is typically made from carbon film deposited on ceramic cores. When current passes through the resistor, a resistance value is created. This value is what regulates the flow of current. Lastly, it is also temperature-sensitive, as the resistance value changes when temperatures change.
