BL01/02/03 series are ferrite beads with lead wires to
produce a high frequency loss for suppression of
noise. Simple construction and easy-to-use, effective
for low impedance circuits such as power supplies and
grounds. Effective also for preventing overshoot and
undershoot of digital signal in clocks or the like,
and suppressing the higher harmonic wave. Suitable for
prevention of abnormal oscillation at high frequency
amplifying circuit.
