Why ferrite core used

Usually, the permeability level in the ferrite core inductors ranges between to 15,, depending on the type of ferrite material used. Thus, ferrite core inductors boast of high inductance as compared to other inductors with air cores.

Also, inductors are a major type of passive linear circuit element besides capacitors and resistors. They contribute in producing electronic circuits of superior quality. So, we prefer to use them over others. Electronic engineers prefer to use ferrite core inductors because of the losses they exhibit and their dependence on frequency levels.

The eddy current losses in the inductors increases exponentially while the hysteresis loss increases linearly with the increase in frequency and flux. Out of the two core losses, the hysteresis loss is the dominant one but up to a frequency level that depends on the performance of the cores, beyond which eddy current loss predominates. Sleeves are usually installed after all cabling has been attached.

For round cabling, a square plastic ferrite sleeve is often used. The core is contained in a hinged plastic casing that opens up to permit the insertion of the cable, then snaps together to secure the ferrite A5 core around the cable to suppress EMIs.

Another option is to use a ferrite sleeve suppression cored with a round plastic casing, sized to fit the cable used. Both the square and round cased ferrite cores attenuate any form of EMI emission and are often used either as a retrofit or for testing purposes when calculating ferrite core filter specifications and design requirements. To begin choosing the correct type of ferrite core, bead, or sleeve you need for your design applications, use the suggested ferrite products in this handy chart.

A single circuit protection on a PCB uses a single, two-lead ferrite bead. Protect multiple adjacent circuits on a PCP. Use a multiline suppressor bead. For installation on outer cables for retrofit or testing purposes, use a square plastic casing ferrite sleeve. For installation on round power cables, use a round plastic casing ferrite sleeve.
