On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Chip Ferrite Beads BLM03/BLM15/BLM18/BLM21/BLM31/BLM41 Series
s
Features (BLM_A Series)
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
relatively low frequencies. Therefore BLM_A series is
effective in noise suppression in a wide frequency
range (30MHz - several hundred MHz).
The small size of BLM03 series (0.6x0.3mm) is
suitable for noise suppression in small equipment
such as PA modules for cellular phones.
