Introduction to Power Inductors

A power inductor, also called an inductor coil or choke inductor, is a passive electronic component consisting of wire wound around a core of ferrite that includes an air gap. This is used to clean up the output from high frequency switch power supplies. Selecting an inductor is more complicated than just choosing the inductance value. To be confident that the inductor will perform in your circuit, there are other specifications that will need to be considered. Learn more about these specifications in the full tech guide.
