Through Hole Resistors

Through hole resistors are one of the most common components found in circuit design. The H81K47FCA is a through-hole resistor manufactured by NXP, and is used in a variety of applications. In this article, we will discuss the various applications of the H81K47FCA, as well as its working principle.

Application Fields of H81K47FCA

The H81K47FCA is designed for use in controlling current in an electrical circuit. It is a voltage-dependent resistor, which means that its resistance changes with the voltage applied to it. This makes it useful in a variety of applications, such as voltage divider networks, voltage regulators, and protection circuits. It is also ideal for uses such as temperature sensing, signal attenuation, and surge protection.

Aside from these, the H81K47FCA is also commonly used as a filter in power supply applications. It helps to reduce high frequency noise coming from the power supply and protect sensitive equipment from damage. It is also commonly used to protect expensive digital circuits from power supply fluctuation.

The H81K47FCA is also widely used in instrumentation and control systems, as it provides a variable response. This makes it ideal for use in linear potentiometers, pressure transducers, and other components that require a variable response.

Working Principle of H81K47FCA

The H81K47FCA is a voltage-dependent resistor, which means that its resistance is dependent on the amount of voltage being applied to it. As the voltage increases, the resistance of the resistor increases as well. This makes it an ideal choice for applications where the resistance needs to be constantly adjusted. The H81K47FCA is designed to withstand voltages up to 25V and is able to operate at temperatures up to 85°C.

The H81K47FCA also has an internal temperature compensation circuit, which helps it maintain a constant resistance over temperature changes. This helps to ensure that the resistor exhibits the same performance over a wide temperature range. The resistor also contains internal self-healing components, which helps reduce the risk of any short-circuits.

The H81K47FCA is also designed with a high current carrying capacity, which makes it suitable for high current applications. It is also designed with a low thermal resistance, which helps to regulate the temperature of the resistor over time.

In conclusion, the H81K47FCA is a versatile through-hole resistor designed for use in a variety of applications. Its voltage-dependent resistance and internal temperature compensation circuit make it an ideal choice for applications where the resistance needs to be constantly adjusted. Its high current carrying capacity and low thermal resistance make it suitable for high current applications.
