BLM18 Series
BLM18H/BLM18E series has a modified internal electrode
structure, that minimizes stray capacitance and
increases the effective frequency range.
s
Equivalent Circuit
s
Features (BLM18H series)
1
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-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 is effective in
suppressing the ringing because resistance
especially grows in the lower frequency.
3. The magnetic shielded structure minimizes cross talk.
(Resistance element becomes dominant
at high frequencies.)
s
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
