Through Hole Resistors: PF2472-110RF1 Application Field and Working Principle

Resistors are fundamental components of electronics circuits. These components come in various shapes, sizes, and ratings. One of the most popular types of resistor is the through hole resistor. From the name itself, these components are composed of a metallic element or a group of these elements soldered into a hole or an opening of a printed circuit board. PF2472-110RF1 is one such through hole resistor, and is mainly used for power application and its operation will be discussed in this article.

PF2472-110RF1 Overview

The PF2472-110RF1 is a surface-mount power resistor. It has a three-finger design, which is used for better heat dissipation. This component is composed of an electrically conductive material, usually metal, in a thin film resistive element. The PF2472-110RF1 is designed for mounting the component directly on a printed circuit board, and it has pins that go through the board, enabling it to make contact with a metal contact surface below. The three-finger design distributes the heat across a large surface area, improving its power handling capabilities.

PF2472-110RF1 Application Field

The PF2472-110RF1 is mainly used in power applications, such as power supplies, DC–DC converters, and other power related applications. It is used in switching applications due to its low inductance and very low thermal resistance characteristics, which allow for more efficient device operation. Additionally, it is resistant to high frequency interference due to its high dielectric withstanding capability.

PF2472-110RF1 Working Principle

The main working principle of the PF2472-110RF1 is to regulate electric current. The current regulation is done by the resistance of the metallic element inside the resistor, which reduces the intensity of the current as the voltage increases. The resistance can be adjusted with the use of a simple potentiometer, thus allowing for precise control of the current as the voltage changes. This makes the PF2472-110RF1 ideal for power applications where the current needs to be regulated and efficiency needs to be maximized.

Conclusion

PF2472-110RF1 is a through hole resistor mainly used for power applications due to its low inductance, high dielectric withstanding capability, and low thermal resistance characteristics. Its working principle consists of regulating the electric current with the resistance of the metallic element inside the resistor, which makes it ideal for power applications where precise control is required.
