BL01, BL02 & BL03 Series

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

s High component density potential

s Double bead BL02RN2 types offered for more effective

noise suppression

s Taped and reeled radial and axial types for automatic

insertion can be provided as well as ammo packaging.

s Axial lead version BL01RN1-A62 available
