Ferrite core

Magnetic core on which the windings of electric transformers and inductors are formed

In electronics, a ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such as inductors are formed. It is used for its properties of high magnetic permeability coupled with low electrical conductivity. Moreover, because of its comparatively low losses at high frequencies, ferrite is extensively used for the cores of RF transformers and inductors in applications such as switched-mode power supplies and ferrite loopstick antennas for AM radio receivers.
