Outline of EM Suppression Filters (EMFLr) for DC Line oferrite Bead nductor Ferrite Bead nductor...p.8 1 BL1 BL2RN1 BL2RN2 BL3RN2 " Chip Ferrite Beads are effective for frequencies ranging from a few MHz to a few GHz. Chip Ferrite Beads are widely used as a low noise countermeasure, as well as a universal noise suppression component. " Chip Ferrite Beads produce a micro inductance in a low frequency range. At high frequencies, however, the resistive component of the inductor produces the primary impedance. When inserted in series in the noise producing circuit, the resistive impedance of the inductor prevents noise propagation.
