o 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.
o 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.
