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.
