Notes
  1. When ordering, please specify termination and packaging codes: e.g. DW3316-685MLD
  2. Inductance is per winding, tested at 10 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using Agilent/HP 8753D network analyzer.
  5. Isat: DC current at which the inductance drops 10% (typ.) from its value without current.

Termination:

  • L = Gold over nickel over phos bronze.
  • T = RoHS tin-silver-copper (95.5/4/0.5)(Special order, added cost)
  • S = non-RoHS tin-lead (63/37)(Special order, added cost)

Packaging:

  • D = 13" reel, machine-ready 
    EIA-481 embossed plastic tape (750 per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
