Through hole resistors are often used to regulate voltage and power supply in electronic circuits as they are effective at dissipating excess energy from a particular current. One of the most common types of through hole resistors is the H4681RBZA. This particular resistor is used for various applications in the electronics industry and this article examines its working principle as well as the fields it is applicable to.

The H4681RBZA is a high-power, high current, film type resistor. It has a significant amount of power-handling capacity, dissipating between 100 and 350 watts. It has a maximum overload temperature of 250°C and a maximum working temperature of 125°C. Its non-inductive construction makes sure that currents flowing through it remain proportional to any applied voltage. It also has excellent stability, providing reliable performance for long periods of time.

One of the most important features of the H4681RBZA is its wide operating range. It has a wide resistance range, from 0.001 ohms to 10 kilo-ohms, making it suitable for most electronic applications. It also has a wide voltage handling range, from 5 volts to 120 volts. Lastly, it has a low TCR (temperature coefficient of resistance), making it suitable for temperature-sensitive applications. This wide range of capabilities makes it a great choice for designers who are always looking for versatile components.

The H4681RBZA is suitable for a variety of applications, such as motor control, power conversion, and protection circuitry in power supplies, home appliances, and audio equipment. It can also be used in metering and instrumentation circuits, and is well-suited for controlling the flow of alternating and direct current. Additionally, it is extensively used in communications systems, voltage regulators, power amplifiers, and temperature controllers.

The primary working principle of the H4681RBZA is its ability to resist the flow of electrons through its metal-oxide construction. This resistance changes depending on voltage or temperature, allowing it to regulate the current and prevent over-load by dissipating excess energy. It also makes sure that signals passing through the circuit remain constant, allowing for reliable operation.

In conclusion, the H4681RBZA is a versatile, high-powered resistor with excellent stability and a wide range of capabilities. It is suitable for many different applications, including motor control, power conversion, protection circuitry, and metering and instrumentation. Its power-handling capacity and metal-oxide construction allows for efficient flow of current and its resistance-changing abilities ensure the signals passing through it are never altered. Therefore, it is a great option for designers who require reliable and high-performance components for their projects.
