A ferrite core is a structure on which the windings of electric transformers and other wound components are formed. It is used for its properties of high magnetic permeability coupled with low electrical conductivity (which helps prevent eddy currents).



There are two broad applications for ferrite cores which differ in size and frequency of operation: signal transformers are of small size and higher frequencies, power transformers are of large size and lower frequencies. Cores can also be classified by shape: there are toroidal cores, shell cores, cylindrical cores, and so on.



The ferrite cores used for power transformers are working in the range of low frequencies (1 to 50 kHz usually) and are quite big in size, can be toroidal, or shell or C shape and are useful in all kinds of switching electronic devices (especially power supplies from 1 watt to 100 watts maximum, since powerful applications are usually out of range of ferritic single core and required grain oriented laminations cores).



The ferrite cores used for signals have a range of applications from 1 kHz to many MHz, perhaps as much as 300 MHz, and have found their main application in electronics.
