On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Chip Ferrite Beads BLM03/BLM15/BLM18/BLM21/BLM31/BLM41 Series
■ Features (BLM_A Series)
The chip ferrite bead BLM series comprises ferrite
beads in the shape of a chip. This ferrite bead
generates a high impedance which at high frequency
mainly consists of a resistance element. The BLM
series is effective in circuits without stable ground
lines because the BLM series does not need a
connection to ground.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
BLM_A series generates an impedance from the
relatively low frequencies. Therefore BLM_A series is
effective in noise suppression in a wide frequency
range (30MHz - several hundred MHz).
The small size of BLM03 series (0.6x0.3mm) is
suitable for noise suppression in small equipment
such as PA modules for cellular phones.
■ Equivalent Circuit
(Resistance element becomes dominant
at high frequencies.)

■ Features (BLM_R Series)
The chip ferrite bead BLM series comprises ferrite
beads in the shape of a chip. This ferrite bead
generates a high impedance which at high frequencies
mainly consists of a resistance element. The BLM
series is effective in circuits without stable ground
lines because the BLM series does not need a
connection to ground.
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
The BLM_R series can be used in a digital interface.
Resistance of BLM_R series especiallly grows in the
lower frequency range. Therefore BLM_R series is less
effective for digital signal waveform at low frequency
range and can suppress the ringing.
■ Equivalent Circuit
(Resistance element becomes dominant
at high frequencies.)

■ Notice (Rating)
[Derating]
In operating temperatures exceeding +85D, derating of
current is necessary for chip Ferrite Beads for which rated
current is 1.5A or over. Please apply the derating curve

EMI Suppression Effect / Description
Ringing is caused on the signal waveform.
Such ringing contains several hundred MHz harmonic components and generates noise.

Level [dBµV]
Comparing initial waveform, ringing is suppressed a little.
However there still remains high level waveform distortion.

Level [dBµV]
BLM18R has excellent performance for noise suppression and waveform distortion suppression.
BLM18R suppresses drastically not only spectrum level in more than 100MHz range but waveform distortion.
