There is an absorbable magnetic ring in the ferrite ring, called the anti-jamming ring. It is a transmission line for digital devices. It is a commonly used anti-interference component in electronic circuit, which has a good inhibition effect on high frequency noise. Ferrite magnetic materials are usually used. The impedance characteristics of anti-interference magnetic ring are different in different frequency environments, and the impedance is smaller at low frequency. When the signal frequency is higher, the impedance of the magnetic ring also increases. Ferrite magnetic ring is made of ferrite materials such as iron oxide, nickel oxide, zinc oxide and copper oxide. The reason why it is called ferrite ring is because it contains ferrite components and is a ring product.
General anti-interference magnetic ring is used for data line or audio line. For example, there are motherboards, cpus and power lights in the computer host case, and the data cables are always in a high frequency working state, leading to a large number of electromagnetic interference signals in the auspicious environment, and the signal intensity is even ten times higher than that outside the case.
Why do I need an anti-jamming ring? In order to improve transmission rate and stability, while reducing transmission line interference to other devices during data transmission, individual products require magnetic loops. If the frequency of the ring is wrong, adding a ring will not work. There are even magnetic rings that work fine on the first day of use, but become saturated on the second day. In this case, more magnetic rings must be added.
