COILCRAFT Wirewound ferrite beads boost attenuation and frequency performance, while enabling smaller solution sizes compared to traditional thick-film chip ferrite beads. Devices come in standard package sizes from 0201 (0603) to 1812 (4532) and are used as low pass filters to eliminate high frequency noise while allowing low frequency signals or dc current to pass through a circuit. Devices feature a ferrite construction and heavy gauge wire for high current handling, while providing extremely low DCR and maintaining high filtering impedance across a wide bandwidth – up to GHz band.
