Instruction: Used to suppress electromagnetic emissions by blocking low-frequency noise and absorbing high-frequency noise, avoiding interference. Widely used in EMI/RFI filters, audio transformers, communications, control circuit equipment, LED lighting, automotive electronics, industrial control, etc.
Ferrite toroid core is a commonly used anti-interference component in electronic circuits, which has a good anti-interference effect on high-frequency noise. and the ferrite rings are made of nickel-zinc ferrites. The Toroid core is used for data cables, audio transformers, communications, control circuit equipment, 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.
