Features

The miniaturization of electronic equipment requires high performance EMI filters which enable high density mounting. BLA31A/B series consists of 4 circuits of ferrite beads. BLA31A/B is suitable for EMI suppression in smaller digital equipment.

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