EMI ferrite bead , also called through hole inductor, use of high loss ferrite, available in a wide range of values and configurations to suit most application. Ferrite bead is a kind of anti-jamming applications the fastest growing components, cheap, easy to use,filtering high-frequency noise were improved significantly.Ferrite beads commonly used in filtering or noise reduction, Coilmaster’s Ferrite Beads RH series with high resistivity and reliable. Ferrite bead can be used to suppress differential mode of noise.
