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 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.  
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 in small equipment such  
as PA modules for cellular phones.
