Through Hole Resistors are highly versatile components, used in a wide range of different applications. The HHV-50FT-52-2M74 is a common example of these electrical components. In this article, we’ll explore its application field and its working principles.

The HHV-50FT-52-2M74

The HHV-50FT-52-2M74 is a through-hole resistor, commonly used in the electrical and electronics industries. Its name is a four character designation— beginning with “H” which stands for “High Voltage,” followed by “FT” indicating the film technology, and concluding with “52” telling us the power rating and “2M74” is the resistance value.

More specifically, this resistor is a non-inductive, non-inductive, axial-leaded resistor composed of metal film that has been thin-film deposited on high quality ceramic cores. The metal film is an alloy composed of a mixture of NiCr and NiAl. The resistor is designed to carry a large amount of current in a very small package and to offer a high degree of accuracy over its entire temperature range.

Application Areas of the HHV-50FT-52-2M74

Due to its durability, size and impressive temperature stability, the HHV-50FT-52-2M74 is ideal for a variety of applications. Abroad, it is regularly used in the military, aerospace and automotive industry. Closer to home, it’s an excellent choice for industrial applications, where the environmental conditions often vary.

It’s also common in power electronics, as a resistor for motor control, motor speed and cyclic systems. In addition, these Through Hole Resistors can be used to increase the gain of amplifier circuits or provide base biasing resistors for a variety of analog and digital circuits.

The Working Principle of the HHV-50FT-52-2M74

The working principle behind the HHV-50FT-52-2M74 is relatively simple. The resistor acts like a bridge between two points in a circuit, allowing electricity to travel from one point to the other but also limiting or “resisting” the flow.

In order to control the amount of resistance, the thin-film is etched with a microscopic conductive pattern that produces a precise resistance value based on its width and the length of the pattern. This technique is often referred to as “laser trimming”.

The thin-film then acts as an electrical insulator to protect the delicate circuits and components from damage due to external factors like heat, electrostatic discharge, radiation and mechanical shock. In addition, the ceramic cores help to absorb the heat generated by the resistor and dissipate it quickly out of the circuit.

Conclusion

The HHV-50FT-52-2M74 is a durable and accurate Through Hole Resistor that can be used in a wide variety of industries. Its metal film construction provides excellent temperature stability, while its electrical insulation helps to protect the circuit from external damage. The working principle is relatively simple, as it acts like a bridge to control the amount of electricity flow.
