Application Scenarios & Design Considerations

EMIFIL (Inductor type) Chip Ferrite Bead (Array) BLA31A/BLA31B Series (1206 Size)

Alternative Part Number

  • BLM31PG471SN1L --: Ferrite bead in the same 1206 package with similar 470 ohm impedance at 100 MHz, suitable for EMI suppression in the same circuit position.
  • MMZ1608B471CTAH0 --: TDK multilayer chip bead with 470 ohm impedance, same manufacturer family but different series naming, offering comparable noise suppression performance.
  • BLM18PG471SN1D --: Compact 0603 ferrite bead with 470 ohm impedance at 100 MHz, a widely available alternative when board space allows a smaller footprint.
  • MPZ3216D471ATA0L --: 1206 ferrite bead with comparable 470 ohm impedance and current rating, suitable for EMI suppression in the same circuit position.
  • HCB1206KF-471T30 --: 1206 high-current ferrite bead with 470 ohm impedance, offering similar filtering performance as a cost-effective alternative.
