Notes
  1. When ordering, please specify termination and packaging codes: e.g. PFL4514-223MEC
  2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter.
  3. DCR measured  at 25°C using a micro-ohmmeter. For other operating temperatures,use this DCR at Temperature calculator.
  4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  5. Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
  6. Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

  • E = Halogen free component. RoHS-compliant matte tin over nickel over silver-platinum-glass frit terminations.
  • Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
  • P = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (1000 parts per full reel).
  • B = Less than full reel
    On reel but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (5000 parts per full reel).
