On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Chip Ferrite Beads BLM03/BLM15/BLM18/BLM21/BLM31/BLM41 Series
■ Features (BLM_A Series)
1
The chip ferrite beads BLM series comprises ferrite
bead 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.
■ Equivalent Circuit
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).
(Resistance element becomes dominant
at high frequencies.)
The small size of BLM03 series (0.6x0.3mm) is
suitable for noise suppression of the small equipment
such as PA modules for cellular phones.

■ Features (BLM_B Series)
The chip ferrite beads BLM series comprises ferrite

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

■ Equivalent Circuit
1
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
The BLM_B series can minimize attenuation of the
signal waveform due to its sharp impedance
characteristics. Various impedances are available to
match signal frequency.
(Resistance element becomes dominant
at high frequencies.)

■ Features (BLM_R Series)
The chip ferrite beads BLM series comprises ferrite
bead 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.
■ Equivalent Circuit
1
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 especially 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.
(Resistance element becomes dominant
at high frequencies.)

The BLM_P series can be used in high current circuits
due to its low DC resistance. It can match power lines
to a maximum of 6A DC.

■ Notice (Rating)
In operating temperatures exceeding +85D, derating of
current is necessary for chip Ferrite Beads for which rated
current is 1500mA or over. Please apply the derating curve
shown in chart according to the operating temperature.
