Notes
  1. When ordering, please specify packaging code: e.g. SD43-104KLC
  2. Inductance measured at 100 kHz, 0.1 Vrms using an Agilent/HP 4284A impedance analyzer or equivalent.
  3. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture. Details
  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:

  • RoHS compliant tin-silver over tin over nickel over silver.

Packaging:

  • C = 7" machine-ready reel
    EIA RS-481 clear plastic tape (500 parts per full reel).
  • B = Less than full reel
    In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.
  • 13" reel, machine-ready 
    EIA RS-481 clear plastic tape. Factory order only, not stocked (2000 parts per full reel).
