Introduction

An Fixed inductor, also known as an electronic inductor, is an electronic component that stores energy in the form of a magnetic field. It consists of insulated wire wound around a core of iron or other magnetic material, such as ferric or ferrite. The principle of operation of an inductor is based on the concept of magnetic induction. When a current flows through an inductor, a magnetic field is created that resists the current flow, thereby increasing the total inductance of the component. This increased inductance is used in many applications, including voltage regulation and smoothing, filtering and switching.

LQH43MN821K03L Application Field

The LQH43MN821K03L Fixed Inductor is mainly used in power supplies, DC-DC converters, high power LED lighting applications, LED lighting systems, switching power supplies, and other applications such as communication devices, medical systems, telecoms, automotive and consumer electronics. This component is a 5mΩ high power output signal, with a coil inductance of 8.2μH. It is designed to provide superior performance in a variety of applications with low power losses during operation.

LQH43MN821K03L Working Principle

The LQH43MN821K03L fixed inductor works on the principle of Faraday\'s Law of Magnetic induction . It is an AC-AC transformer, consisting of two coils: a "primary" coil and a "secondary" coil. When electric current runs through the primary coil, it creates an electromagnetic field. This electromagnetic field induces a current in the secondary coil. The output current, or "induced" current, is then amplified due to the ratio of the number of turns in the primary to the number of turns in the secondary.

It also works on the principle of electromagnetic field induced by Faraday\'s law of electro-magnetic induction. When a current runs through a primary coil, it produces a magnetic field with a changing flux. This changing flux induces an electric current in the secondary coil. The output current is proportional to the amount of flux passing through the coil and is amplified due to the turns ratio of the primary to the secondary coil.

Conclusion

The LQH43MN821K03L fixed inductor is an important electronic device used in many applications in the field of electronics and telecommunications. Its main function is to provide flux, voltage and current control in power supplies, DC-DC converters and high-power LED lighting applications. It works on the principle of Faraday\'s Law of Magnetic induction and electro-magnetic induction and is a useful component in many electronic applications.
