A ferrite bead (also known as a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke ) is a type of choke that suppresses high-frequency electronic noise in electronic circuits. Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices.
