Advantage: Ferrite cores are dense, homogeneous ceramic structures made by mixing iron oxide (NiZnFe2O4) with oxides of nickel, zinc. Have very high permeability and low losses, can work at high frequencies
Instruction: Used to suppress electromagnetic emissions by blocking low-frequency noise and absorbing high-frequency noise, avoiding interference
Application: Widely used in EMI/RFI filters, audio transformers, communications, control circuit equipment, LED lighting, automotive electronics, industrial control, etc.
NOTE: The more the number of coiled cables, the better the effect of suppressing interference with lower frequencies, the weaker the effect of suppressing noise with higher frequencies
