Features (BLM18H series)

1. BLM18H series realizes high impedance at 1GHz and

is suitable for noise suppression from 500MHz to

GHz range. The impedance value of HG/HD-type is

about three times as large as that of A/B-type at

1GHz, though the impedance characteristic of

HG/HD-type is similar to A/B-type at 100MHz or less.

2. HG-type is effective in noise suppression in wide

frequency range (several MHz to several GHz).

HB/HD-type for high-speed signal line provides a

sharper roll-off after the cut-off frequency.

HK-type for digital interface and HE-type for

optical pickup modules are effective in suppressing

the ringing because resistance especially grows in

the lower frequency.

3. The magnetic shielded structure minimizes crosstalk.

Features (BLM18E series)

1. Low DC Resistance and a large Rated Current are

suitable for noise suppression of the driver circuit.

2. Excellent direct current characteristics

3. Thin type (t=0.5mm) is suitable for small and low

profile equipment such as DSC, cellular phones
