Introduction

Fixed inductors are components used in electronics that stores energy in the form of a magnetic field when a current passes through it. They can be broadly classified into two main categories: air-core inductors, where the magnetic field is generated in the air gap between two metal plates, and core-based inductors, where the magnetic field is created using a ferromagnetic material like iron or steel. The 108R-104KS is a fixed inductor belonging to the core-based inductor family, and can be used in a variety of applications.

Overview of 108R-104KS

The 108R-104KS is a fixed inductor that is specially designed for use in high current, high frequency applications such as telecommunications, switch mode power supplies (SMPS), and other low-noise circuits. It is composed of an iron-powder core surrounded by a ferrite material, which holds the magnetic field generated when a current passes through it. The ferrite core material is then coated by a number of thin copper wires, which helps in reducing noise and increasing the current capacity of the inductor. The 108R-104KS inductor is available in a variety of inductance values and current ratings, ranging from 0.8mH to 330mH and 0.1A to 10A.

Application Field and Working Principle of 108R-104KS

The 108R-104KS is mainly used in high-current, high-frequency applications such as mobile communications, and power converters. It can also be used in RF circuits and other applications that require low noise and high current capacity.The working principle of the 108R-104KS is based on Faraday’s law of induction. When a current passes through it, a magnetic field is generated in the air gap between the iron-powder core and the ferrite material, which induces an opposing voltage in the copper wires. This opposing voltage reduces the current passing through, thus acting as an inductor. The rate at which the current is reduced depends on the inductance of the 108R-104KS inductor.The 108R-104KS also provides a high degree of EMI and RFI protection due to its magnetic shielding, which prevents electromagnetic interference from affecting the output signal. It also provides protection against overloading, and can handle high inrush currents without damage.

Conclusion

The 108R-104KS is a fixed inductor designed for high current, high frequency applications. It is composed of an iron-powder core surrounded by a ferrite material, and is then coated by a number of thin copper wires. The inductor works based on Faraday’s law of induction, which generates a magnetic field in the air gap between the iron-powder and ferrite material, which induces an opposing voltage in the copper wires. The inductor also provides EMI and RFI protection due to its magnetic shielding, and can handle high inrush currents without damage. The 108R-104KS is a versatile and reliable component that can be used in many applications.
