Fixed inductors are electric components that are used to store electrical energy in a magnetic field when an electrical current is applied through it. The magnetic field created within the inductor is proportional to the magnitude of the current being sent through it, thus creating a resistance to fluctuations in current flow, and a reactance to changes to the frequency of the alternating current. BRC2518T220M is an example of a fixed inductor.

Working Principle of BRC2518T220M

The working principle of BRC2518T220M follows the basic laws of electromagnetism. When an electric current is sent through the coil of the inductor, a magnetic field is created in the ferrite core, thereby causing a reaction in the local space. This reaction produces a counter-emf proportional to the rate of change of the current. In other words, when the current in the inductor increases, the generated magnetic field increases as well, thus opposing the change. This phenomenon is known as high inductance. The main purpose of the inductor is to maintain constant current level in a circuit and act as a filter in order to reduce ripples in voltage.
