Notes
  1. When ordering, please specify termination and packaging codes: e.g. 1812LS-105XJLC
  2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A and a Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces. Inductance at 0.79 MHz measured using an Agilent/HP 4192A and Coilcraft SMD-B test fixture.
  3. Q read at test frequency directly on an Agilent/HP 4192A LF impedance analyzer and a Coilcraft SMD-B test fixture.
  4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  5. DCR measured on a Cambridge Technology micro-ohmmeter.  For other operating temperatures, use this DCR at Temperature calculator.
  6. 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.

Termination:

  • L = RoHS compliant silver-palladium-platinum-glass frit.
  • R = RoHS compliant, matte tin over nickel over silver platinum-glass frit.
  • 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:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (600 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 C.
  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel).
