Fixed inductors are electronic components that store electrical energy either in the form of current or magnetic field. The LAL04KB4R7K is a type of fixed inductor with a range of specific features and uses. This article outlines the application field and working principle of this particular inductor.

Application Field

The LAL04KB4R7K fixed inductor is designed for a wide range of applications. It is most commonly used in audio, radio, and power circuits, as well as a variety of other applications. It is suitable for high frequency switching power supplies, voltage regulators, AC/DC power converters, voltage transformer circuits, and audio frequency circuits. Additionally, it is often used to improve the performance of industrial power systems and motor drive systems.

Working Principle

Fixed inductors use electromagnetic induction to operate. This phenomenon occurs when an electric current is passed through a conductor and creates a magnetic field around it. This magnetic field then induces an electric current in a second conductor that is placed in the first conductor\'s magnetic field, creating a flow of electricity. In the case of the LAL04KB4R7K, this electric current is stored in the inductor as a current or magnetic field, depending on how it is used.

The LAL04KB4R7K\'s inductance is determined by the size and shape of the inductor, as well as the number of turns of wire around the core. Additionally, the inductance is affected by the number of cores and the type of magnetic material used in the core. The inductance is also affected by the permeability of the core material, which is determined by the permeability of the air around the core.

In addition to inductance, the LAL04KB4R7K has a nominal current rating of 4A. This sets the maximum level of current that it can handle without getting overly hot. Additionally, the inductor has a self-resonance frequency of 30MHz. This determines how quickly it can absorb and release energy from the surrounding environment.

The LAL04KB4R7K fixed inductor is a versatile, high-performance component that is suitable for a wide range of applications. It is designed to store electrical energy in the form of current or magnetic field and features a high current rating and self-resonant frequency for improved performance.
