CG01-I
Ferrite beads are used for noise suppression in car radios,
digital control equipment and for the prevention of spurious
oscillation in radio frequency amplifiers. These ferrite bead
inductors are devices which can effectively be used on
printed circuit boards where high component density is
essential. Taped and reeled types are also available for
automatic insertion. Radial leaded units can be classified
into two types — one using a single ferrite bead and the
other using two ferrite beads.
FEATURES
I
