Fixed Inductors

A fixed inductor is an electronic component that helps filter or store energy in an electrical circuit. The inductor can be thought of as a capacitor that stores energy in its magnetic field, rather than in the electrical field between two capacitors. A variety of fixed inductors are available in a range of sizes, inductance values and dielectric materials.

The HK2125R18K-T is an example of a fixed inductor, characterised with a high power rating and low DC resistance. It is a surface mount inductor ideal for use in power line filters and switching power supplies. As a low profile, narrow foot print device, it can be used in automotive, audio and motor control applications.

HK2125R18K-T Application Field and Working Principle

The HK2125R18K-T is a thick film, ferrite core, high power, low resistance, surface mount inductor. It offers high rated inductance of 18μH±20%. The major application fields are power filters and switching power supply. It is also used in automotive, audio and motor control applications.

The inductor functions by providing electrical current with an inductance. This is achieved when a current is applied through the inductor, which creates an inductive potential that stores energy in the form of a magnetic field. When the current is removed, the stored energy is released back into the electrical circuit.

The working principle of the HK2125R18K-T is based on the principle of the mutual inductance of two circuits. The inductor has two coils, or windings, around a core. When a current is passed through one winding, the other winding acts as the stationary coil, and an electric field develops between them. This electric field allows for energy to be stored in the form of a magnetic field. When the current is removed, the stored energy is released back into the electrical circuit, providing an inductance to the circuit.

The HK2125R18K-T is characterised by high power ratings, low DC resistance, low profile, and a narrow footprint. It offers a wide range of applications, making it suitable for both high power and low power circuits. Also, thanks to its efficient and high power-handling capability, it can be used for high-speed, large-scale power conversion, switching power supplies, and power line filters.

In conclusion, the HK2125R18K-T is a practical and reliable high power, low DC resistance, surface mount inductor ideal for applications such as power filters and switching power supplies. It is highly efficient and offers great power handling capability, making it suitable for high-speed, large-scale power conversion.
