Inductors, in most cases, can be divided into two categories: fixed and adjustable. The PM2120-470K is a type of fixed inductor, meaning its properties cannot be changed. This type of inductor is used in a variety of applications as it provides an optimal performance. In this article, we will discuss the application field and working principle of the PM2120-470K.

What is an Inductor?

An inductor is a type of passive component that stores energy in a magnetic field when a current passes through it. It is made of several turns of a wire wound around a core. The core is usually made up of an iron material, while the winding is made up of a copper wire. An inductor can be used in electrical circuits to create an inductance, which is the resistance to changes in current.

Application Field of the PM2120-470K

The PM2120-470K is a general-purpose fixed inductor. It is designed to provide a large amount of inductance for various applications such as power supplies, alternating current circuits, step-up converters, and many more. The 470K has a rated inductance of 450uH, which is suitable for any low-frequency applications. Furthermore, the 470K has a low DCR (DC resistance) which improves its power efficiency.

Working Principle of the PM2120-470K

The basic working principle of a fixed inductor is determined by Faraday’s laws of induction. When a current is applied to an inductor, a voltage is induced onto it in the opposite direction of that current. This voltage is directly proportional to the rate of change of the current, an effect known as self-inductance. The 470K’s rated current of 1.5 A allows it to be used in applications that require high currents. Additionally, the parameters of the inductor allow for a wide range of applications.

Conclusion

In conclusion, the PM2120-470K is a type of fixed inductor that is widely used in many applications. It is capable of providing a large amount of inductance, which is necessary in many power-conversion designs. The PM2120-470K is designed with a low DCR for increased power efficiency and its rated current of 1.5 A helps it provide inductance in high current applications. Its working principle is based on Faraday’s laws of induction.
