Black plastic enclosed ferrite core for 1/2" AC power cords Dimensions: 1-3/8"L x 3/4"D Easy to install, simply snap around cord Black plastic enclosed ferrite core for 1/2" AC power cords. Easy to install, simply snap around cord. Helps reduce EMI on AC power lines. Cable core filter will provide common-mode filtering for multi-strand cables and differential mode filtering for single conductors. Dimensions: 1-3/8"L x 3/4"D

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.

Ferrite is a class of ceramic material with useful electromagnetic properties and an interesting history. Ferrite is rigid and brittle. Like other ceramics, ferrite can chip and break if handled roughly. Luckily it is not as fragile as porcelain and often such chips and cracks will be merely cosmetic. Ferrite varies from silver gray to black in color. The electromagnetic properties of ferrite materials can be affected by operating conditions such as temperature, pressure, field strength, frequency and time.

There are basically two varieties of ferrite: soft and hard. This is not a tactile quality but rather a magnetic characteristic. 'Soft ferrite' does not retain significant magnetization whereas 'hard ferrite' magnetization is considered permanent.
