Chip Ferrite Bead Inductor BLM Series
K01E23.pdf 97.10.03
The chip ferrite bead inductor BLM 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 BLM series is
effective in circuits without stable ground lines because the
BLM series does not need a connection to ground.
Chip sizes of 1.0g0.5, 1.6g0.8, 2.0g1.25, 3.2g1.6 and
4.5g1.6mm are cataloged. (The BLA series of array type
chip ferrite bead inductors is also cataloged.)
The nickel barrier structure of the external electrodes
provides excellent solder heat resistance. Both flow and
reflow soldering methods can be employed.
cFEATURES
The BLM series comprises the A series (standard), the B
series (for high freq. signal), and the P series (high current).
1. BLMMMA series-Standard
The BLM-A series generates an impedance down to
relatively low frequencies. The impedance consists of a
resistance element and prevents signal ringing. Various
impedances are available to match signal frequency.
2. BLMMMB series-High Frequency
The BLM-B series can minimize attenuation of the signal
wave form due to its sharp impedance characteristics.
Maximum signal frequencies ranging from 10MHz to
100MHz are available.
3. BLMMMP series-High 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.

V1 has sharp impedance characteristic suitable for high speed lines.(At Maximum Signal Frequency insertion loss is 6dB in 50Ω impedance circuit.)
V2 marked items are designed for ultra-high speed signal lines such as next generation memory interface. Since these impedance curve rise from several
V2 hundred MHz,these items can suppressnoise unless the misoperation of circuits. (At Maximum Signal Ferquency, impedance is 22Ω which is used as
Dumping.)
