On-Board Type (DC) EMI Suppression Filters(EMIFILr)
Chip Ferrite Beads Arrays BLA31A/BLA31B Series
3
The miniaturize of electronic equipment requires high
performance EMI filters which enables high density
mounting. BLA31A/B series consists of 4 circuit of
ferrite bead inductor.
BLA31A/B is suitable for EMi suppression in smaller
digital equipment.

1. BLA31A/B have 4 circuits in 3.2x1.6mm body with 0.8mm
pitch.
in mm
2. Provides attenuation across a broad frequency range.
Two types of impedance are available which meets
general signal line and high speed signal line.
3. Original inner electrode structure enables extra low
crosstalk.
4. The nickel barrier structure of the extermal
electrodes provides excellent solder heat resistance.
Both flow and reflow soldering methods can employed.
