1. Introduction to Fixed Inductors

A fixed inductor is an electrical component which uses magnetic fields to store energy. It is a passive device that stores energy in the form of an electromagnetic field or current. Generally, they are made up of a coil of wire and a ferromagnetic core such as iron or ferrite. The coil of wire, usually made of copper or aluminum, has a certain number of turns. This number of turns determines the value of the inductor when connected to a source and a load. The core material is important to the electrical characteristics of the inductor.The main purpose of a fixed inductor is to store energy. It can be utilized to create a voltage or current in a circuit depending on the configuration and application.

4. Working Principle of SRR6028-221Y

The SRR6028-221Y fixed inductor operates by storing energy in the form of an electromagnetic field or current. When a DC voltage is applied to the inductor, a current flows through it. This current creates a magnetic field which is proportional to the current.The magnetic field stores energy due to Faraday’s law of induction. This stored energy can be retrieved by removing the voltage source. This creates a collapse of the magnetic field, which results in the release of the stored energy as current back to the source.

5. Conclusion
