Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices. See more Ferrite beads prevent electromagnetic interference (EMI) in two directions: from a device or to a device. A conductive cable acts as an antenna – if the device produces radio-frequency energy, this can be transmitted … See more • Braid-breaker • Balun • Electromagnetic interference See more Ferrite beads are used as a passive low-pass filter, by dissipating radio frequency (RF) energy as heat, by design.
