Notes
  1. When ordering, please specify termination and packaging codes: e.g. 0603AF-103XJRW
  2. Inductance measured at 0.1 Vrms, using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
  3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  4. DCR measured at 25°C using a Cambridge Technology Micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  5. Irms: Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Because of their open construction, these parts will not saturate.
  6. Each part is marked with a single dot. The color dots are not unique identifiers and correspond to multiple inductance values.

Termination:

  • R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.
  • Q = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (Special order, added cost)
  • P = Not RoHS Sn/Pb (63/37) (Special order, added cost)

Packaging:

  • W = 7” machine-ready reel. EIA-481 punched paper tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • Y = 13″ machine-ready reel. EIA-481 punched paper tape. Factory order only, not stocked (10000 parts per full reel).
  • U = 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 U to W.
