Ferrite beads are passive components used in electronic circuits to suppress high-frequency interference signals. Also known as "attenuation beads," they act as passive low-pass filters and systematically sort signals above the cutoff frequency. This significantly improves signal quality.
Communication devices or even the functionality of computer software are particularly dependent on clean signal transmission, which is why ferrite beads are often used in these areas. Ferrite beads differ in terms of their material composition, their physical size and shape, and their impedance and cutoff frequency.
