On-Board Type (DC) EMI Suppression Filters(EMIFILr)

GHz Noise Suppression Chip Ferrite Beads BLM18H Series

0.4±0.2

The chip ferrite bead BLM18H series comprises ferrite

bead inductors in the shape of a chip. This inductor

generates a high impedance which at high frequencies

mainly consists of a resistance element. The BLM18H

series is effective in circuits without stable ground

1.6±0.2

lines because the BLM18H series does not need a

0.8±0.15

connection to ground.

■ Features

in mm

The BLM18HG, BLM18HD series has a modified internal

electrode structure, that minimizes stray capacitance

and increases the effective frequency range. Impedance

values of 1000 ohm can be attained at frequency of 1Ghz

and greater.

1. The BLM18HG, BLM18HD series is similar to the

exiting BLM at frequency below 100MHz, however at

1GHz the impedance is approx. 3 times larger.

2. The BLM18HG is intended for standard signal lines

as this series provides significant impedance across

a broad frequency range. The BLM18HD provides a

sharper roll-off after the cut off frequency,

therefore this series is ideal for high speed signal

lines.

3. The magnetic shielded structure minimizes crosstalk.

The BLM18HK series is chip ferrite beads for GHz range

noise suppression of digital interface.The BLM18HK

series has a modified internal electrode structure that

minimizes stray capacitance and increases the effective

frequency range.

Resistance especially grows in the lower frequency range,

therefore BLM18HK series cansuppress the ringing.

■ Features

1. The BLM18HK series is realized high impedance at 1GHz

and suitable for noise suppression from 500MHz to GHz

range.

2. The BLM18HK series is effective in suppressing the

ringing because resistance especially grows in the

lower frequency.

3. The magnetic shielded structure minimizes cross talk.

■ Applications

• Interface line of computer that has high-speed CPU &

high-speed bus and other digital equipment like HDD.

• Suitable for noise suppression from 500MHz to GHz

range.
