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.

Advantage:
The annular structure is formed by the use of nickel-zinc ferrite in the toroid core, which is wear-resistant and has a long service life. Capable of working in high-frequency currents, allowing useful signals to pass through normally and filtering out interference from radio signals.

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.

NOTE:
The more the number of coiled cables, the better the effect of suppressing interference with lower frequencies, and the weaker the effect of suppressing noise with higher frequencies.
