incredible! These cold knowledge of ferrite cores

The most widely used soft magnetic materials are ferrosilicon (silicon steel) and various soft ferrite cores. Ferrite core is a kind of high-frequency magnetic material (the same principle as steel, only used in high-frequency environment), mainly for high-frequency transformers, high-frequency magnetic ring (anti-jamming) and so on, increase the guide Magnetism, improve the inductance quality factor, use inside the transformer. The higher the permeability of the ferrite, the greater the impedance of the low frequency and the smaller the impedance of the high frequency. According to different requirements, different processes can be chosen to make the magnetic ring.

The ferrite core is mainly composed of three kinds of metal elements: iron (Fe), manganese (Mn), and zinc (Zn), and is often referred to as manganese-zinc ferrite. The ferrite core is made of a dense and homogeneous ceramic structure of non-metallic magnetic material with low coercive force, also known as soft ferrite. Ferrites have the advantage of high permeability and high resistance and low eddy current losses over a wide range of frequencies. These material properties make ferrite an ideal material for applications such as high-frequency transformers, wide-band transformers, tunable inductors, and other high-frequency circuits from 10 kHz to 50 MHz.
