This is a magnetic ring specifically designed for wires, also known as a ferrite core ring. It is made of nickel zinc material, no magnetism, and is only used for EMI anti-interference. The outer diameter size is 14.2mm, the hole is 4.5mm, and the height is 28.5mm. If you need a quotation or other sizes, please contact customer service.
Note: Ferrite anti-interference cores can also be used in the signal line to suppress the transmission of noise between components or equipment. Only the impedance of the signal line is generally greater than the power line, so the interference suppression effect will be less obvious than in the power line to come.
