The miniaturization of electronic equipment requires high performance EMI noise suppression filters which enable high density mounting.  Murata's ferrite bead array filters are available in two sizes: EIA 0804 size (BLA2AA / AB) has 4 circuits with a 0.5mm pitch and EIA1206 size (BLA31A / B) has 4 circuits with a 0.8mm pitch.  All array series are offered in a variety of impedances and current ratings with a wide operating temperature range of -55 degrees  to +125 degrees C.

Features & Benefits:

  • Suitable for high density mounting or where board space is at a premium - consists of 4 circuits of ferrite beads.
  • Provides attenuation across a broad frequency range.
  • Innovative design of electrode structure enables very low cross talk.
  • Wide operating temperature range of -55 to +125 degrees C.
  • RoHS compliant.


  • PDA's
  • Netbook PC's.
  • Portable Electronic Devices
