Covers Every Application in High Speed Signal Line,
DC Power Lines and High-GHz Noise Suppression
The chip ferrite bead BLM series is comprised of 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. BLM series is effective in circuits
without stable ground lines because BLM series does not
need a connection to ground.
!Features
BLM series is comprised of R series (for digital interface),
A/T series (for standard), B series (for high speed signal),
P/S series (for large current), H/E series (for GHz band
noise suppression), and G series (for High-GHz band noise
suppression).
1. BLM--R series – For Digital Interface
2. BLM--A/T series – For General Use
3. BLM--B series – For High Speed Signal
Chip Ferrite Bead BLM Series
On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Impedance Characteristics
BLM-R series can be used in 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.
BLM-A series generates an impedance from the relatively
low frequencies. Therefore BLM-A series is effective in
noise suppression in the wide frequency range
(30MHz – several hundred MHz).
BLM-B series can minimize attenuation of the signal
waveform due to its sharp impedance characteristics.
Various impedances are available to match signal
frequency.

Chip sizes of 0.4x0.2, 0.6x0.3, 1.0x0.5, 1.6x0.8, 2.0x1.25,
3.2x1.6 and 4.5x1.6mm are cataloged. (BLA series of array
type chip ferrite beads is also cataloged.)
The nickel barrier structure of the external electrodes
provides excellent solder heat resistance.
4. BLM--P/S series – For Large Current
5. BLM--H/E series – For GHz Band Noise Suppression
6. BLM--G series – For High-GHz Band Noise Suppression

BLM-P/S 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.
BLM--H/E series has horizontal wire wound structure
that minimizes stray capacitance and increases the
effective frequency range.
BLM--G series has improved the performance in High-
GHz frequency area using newly developed low dielectric
ferrite material.
