EMI LEADED FILTERS
FERRITE BEAD INDUCTORS
BL01, BL02 & BL03 Series
244 CG01-J
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
■ High component density potential
■Double bead BL02RN2 types offered for more effective
noise suppression
■Taped and reeled radial and axial types for automatic
insertion can be provided as well as ammo packaging.
■Axial lead version BL01RN1-A62 available
APPLICATIONS
Micro computer, switching regulators, digital control
equipment, car radios, car stereos, etc.
