Ferrite Y30BH Ring Magnet 

Ferrite magnetic rings mainly include nickel - zinc ferrite magnetic rings and manganese - zinc ferrite magnetic rings. The magnetic ring of ni-zn ferrite is suitable for restraining electromagnetic interference at high frequency. The magnetic ring of manganese zinc ferrite is suitable for restraining electromagnetic interference at low frequency end. 

The higher the magnetic conductivity of ferrite, the higher the impedance of low frequency and the lower the impedance of high frequency. We can choose different skills to make magnetic rings according to our different needs. The magnetic ring can produce different impedance at different frequencies, and the impedance of the magnetic ring increases sharply as the signal frequency increases. 

Secondly, since it does not require grounding as other filtering methods do, there is no special requirement for this description. It is also very convenient to use, it can be directly mounted on the cable that needs filtering. When used as a common-mode choke, the signal distortion will not be formed, which is very valuable for the magnetic ring wires that transmit high frequency signals. The method of making multipole magnetic rings is to use the method of heat processing to make circular magnets with isotropic or anisotropic diameters. The inner circle of the ring magnet is polygonal, and the thickness of the ring wall changes periodically. Compared with the existing skills, its advantages lie in convenient installation, accurate positioning of the device and small alveolar effect. At high temperature or high speed, the magnetic degaussing effect is small and not easy to fall off. 

The larger the inner and outer diameter difference of ferrite magnetic ring is, the longer the axial direction is and the greater the impedance is. But the inner diameter must be tight. Therefore, in order to obtain a large attenuation, the larger magnetic ring should be used as far as possible under the condition that the inner diameter of ferrite magnetic ring is wrapped tightly.
