Through Hole Resistors are a type of power resistors, among the most commonly used resistors, which are intended for installation in printed circuit boards. In the electronics industry, they play a critical role in electrical and electronic applications. The HHV-50FT-52-39M2 is one such type, and in this article we’ll look at its application field and working principle.

Overview

The HHV-50FT-52-39M2 is a commercial through hole power resistor made from a combination of a high-voltage carbon film, an epoxy coating, and a metal core. The resistor is a stamped one-piece construction, creating a flat shape that improves heat dispersion and dissipates more efficiently than other resistor types. It is designed with power ratings up to 2A for overloads and up to 15A for steady DC operation at 25°C.

Applications

Due to its high-voltage rating and efficient heat dissipation characteristics, the HHV-50FT-52-39M2 is primarily used in high-voltage applications such as power supplies, industrial automation, and medical equipment. In addition, it is well-suited to applications that require larger resistances, such as lighting fixtures and electrical motors.

The HHV-50FT-52-39M2 is also a popular choice for use in multiple-load applications, such as high-voltage DC motor windings and between different phases of a three-phase system. This is due to its wide resistance range of up to 1,000 Ohms as well as its low DC output resistance levels.

Working Principle

The working principle of the HHV-50FT-52-39M2 is based on the principle of the standard Ohm\'s law, which states that the current is always directly proportional to the voltage and inversely proportional to the resistance. In terms of the resistor itself, in order to generate a resistance, the voltage output of the device must be regulated according to the resistance of the resistor. This process is achieved by varying the temperature of the device and the material used to create the resistor.

The HHV-50FT-52-39M2 effectively performs its resistance regulation by using carbon film on the device which changes its electrical resistance characteristics depending on the temperature it is exposed to. As the temperature increases, the resistance decreases; similarly, as the temperature decreases, the resistance increases. This regulation allows for the device to maintain a consistent resistance value even as the temperature of the environment fluctuates.

Safety Features

The HHV-50FT-52-39M2 is designed with a considerable number of safety features. Firstly, its construction and design ensure that it is highly resistant to mechanical vibrations and short-circuiting, which can damage other resistors. Secondly, the construction also allows for efficient heat dissipation, which is important in high-voltage operations. Finally, the device is able to power on and off quickly, reducing the risk of instantly overloading the system.

Conclusion

The HHV-50FT-52-39M2 is a type of through hole resistor that is used for a variety of high-voltage applications. Its combination of high-voltage carbon film, epoxy coating, and metal core ensures that it is capable of regulating a consistent resistance value even in fluctuating conditions. In addition, its construction and design makes it highly resistant to sudden power fluctuations, vibrations, and short-circuiting. Thanks to these features, it provides an efficient and safe operation in all high-voltage applications.
