Fixed inductors are electronic components used to store electric energy in the form of a magnetic field. PM105-181K-RC is a type of fixed inductor, which is widely used in various electronic circuits for many purposes. This article will discuss the application field and working principle of PM105-181K-RC.

PM105-181K-RC is a surface-mounted variable-reluctivity inductor specifically designed for high-frequency power supply applications, such as AC/DC power converters. It can be used to limit the inrush current and voltage rates, as well as reduce the peak-to-peak voltage overshoot in high frequency converters. Moreover, PM105-181K-RC is an ideal choice for any switched mode power supply (SMPS)s that require inductors. It is also used in automotive electronic control units, cell phones, and other consumer electronics.

The construction of PM105-181K-RC uses a rectangular core, which is wound with multiple turns of wire. This winding is coated with a protective layer that prevents wear and tear due to vibration or mechanical shock. Its mechanical construction is reliable and has minimal losses, making it suitable for use in high-frequency switching power supplies. In addition, PM105-181K-RC includes a ferrite core, which ensures its high inductance without taking up too much space. The size of the core is also quite small, allowing the inductor to be incorporated in extremely tight spaces.

As for the working principle of PM105-181K-RC, it is based on Faraday\'s law of induction, which states that the opposite current is induced in the wire due to the changing magnetic flux. The working principle of PM105-181K-RC also relies on the idea of variable reluctance, which is when a metal rod is inserted into the core of an inductor that changes its reluctance in response to the applied electrical current. The core of PM105-181K-RC contains a ferrite material, which allows the inductor to have a high inductance with minimal losses. When electric current is applied to the inductor, the varying reluctance of the ferrite core induces a current in the wire, creating a magnetic field stored energy.

To sum up, PM105-181K-RC has multiple advantages when compared to other fixed inductors. It is suitable for high frequency power supplies and is capable of limiting inrush current and voltage rates, reducing peak-to-peak voltage overshoot. Additionally, it has a small form factor and features a ferrite core, which ensures its high inductance without taking up too much space. Moreover, its working principle follows Faraday’s law of induction and relies on the concept of variable reluctance. All these benefits make PM105-181K-RC a popular choice for power supply applications.
