On-Board Type (DC) EMI Suppression Filters(EMIFILr)
Chip Ferrite Bead BLM Series
Essential for Noise Suppression in High Speed Signal
Lines and DC Power Lines
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.
!Features
The BLM series comprises the R series (for digital interface),
the A series (for standard), the B series (for high speed
signal), the P series (for large current), and the H/E series
(for GHz range noise suppression).
1. BLM--R series – For Digital Interface
The 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.
2. BLM--A series – For Standard
The BLM-A series generates an impedance from the
relatively low frequencies. Therefore the BLM-A series is
effective in noise suppression in the wide frequency
range (30MHz – several hundred MHz).

Chip sizes of 0.6Z0.3, 1.0Z0.5, 1.6Z0.8, 2.0Z1.25, 3.2Z1.6
and 4.5Z1.6mm are cataloged. (The BLA series of array
type chip ferrite beads is also cataloged.)
The nickel barrier structure of the external electrodes
provides excellent solder heat resistance.
3. BLM--B series – For High Speed Signal
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.
4. BLM--P series – For Large Current
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 (BLM41P).
5. BLM18H/E series – For GHz Range Noise Suppression
The BLM18H/E series has a modified internal electrode
structure that minimizes stray capacitance and increases
the effective frequency range.
