Fixed inductors are electronic components commonly used in various kinds of electronic circuits. The 4379-393KS is a particular type of fixed inductor used in applications ranging from radio frequency circuits to audio amplifiers. In this article, we will discuss its application field and working principle.

Application field

The 4379-393KS is a chip-shaped ferrite core inductor with an excellent resistance to high frequencies. It is often used in radios and communication equipment in order to bring down the impedance of the antenna circuit to obtain a stronger signal reception. In addition, due to its high-frequency characteristics, this inductor is also widely used in audio amplifiers, especially in low-noise audio amplifiers. In these amplifiers, the 4379-393KS provides efficient filtering of low-frequency noise signals, allowing for a more clean and defined sound output.

Working principle

The working principle of the 4379-393KS is relatively simple. Its ferrite core is made of an iron-oxide material, making it a magnetic material that facilitates current flow. The inductor works on the principle of electromagnetic induction, where when a changing current passes through a conductor it induces a magnetic field that opposes the changes in the current. This opposition to the current results in increased voltage drop. This voltage drop is what makes the 4379-393KS inductor so effective in RF circuits and audio amplifiers.

The 4379-393KS has a maximum rated inductance of 1.2µH. This indicates that the inductor has the ability to store energy as long as the current remains constant. This stored energy is then released across the inductor when the current decreases, meaning that the inductor acts as a sort of regulator to keep the current at the necessary levels. This storage and release of energy is what makes the 4379-393KS so effective in high-frequency applications.

To conclude, the 4379-393KS is a highly effective fixed inductor used in a variety of applications, most importantly high-frequency radios and audio amplifiers. It works on the principle of electromagnetic induction, where its ferrite core stores energy which can be released when necessary in order to regulate the current. This combination of high-frequency characteristics and voltage regulation makes the 4379-393KS one of the most reliable and effective fixed inductors available.
