The power inductor is a type of passive electrical device. It is coiled with copper wire and has a ferrite drum. This inductor's terminals, commonly known as pads, are intended for surface attachment. The inductor is also magnetically shielded. This inductor also has the greatest humidity tolerance rating of 1. Ideally, this inductor is used as a DC-DC converter inductor in laptop PCs, game machines, and other similar devices.
