Ferrite  Core 

       Selection of ferrite magnetic core: According to the frequency of interference to be suppressed, select ferrite materials with different permeability. The higher the permeability of ferrite, the larger the impedance of low frequency and the smaller the impedance of high frequency. According to different requirements, different processes can be selected to manufacture magnetic rings. The magnetic core  has different impedance characteristics at different frequencies, and the impedance is generally very small at low frequencies, and the impedance of the magnetic ring increases sharply when the signal frequency increases
