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). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
