  1. When ordering, specify tolerance, termination and packaging codes: 0402CS-R12XJRW
  2. Inductance measured at 250 MHz using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer.
  3. G = 2%, J = 5%
  4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
  5. For SRF >6 GHz, measured using an Agilent/HP 8722ES network analyzer and a Coilcraft SMD-D test fixture. For SRF ≤6 GHz, measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  6. DCR measured on a micro-ohmmeter.
  7. 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.

  • R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.

    RoHS compliance expiring. Last order June 2021:
    E = Ag/Pd/Pt-glass frit. Not for new designs.
    L = Not halogen-free. Ag/Pd/Pt-glass frit. Not for new designs.
  • T = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (Special order, added cost)
  • S = Not RoHS Sn/Pb (63/37) (Special order, added cost)


  • 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).
  • Q = 7" machine-ready reel
    EIA-481 punched paper tape (5000 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.
