  1. When ordering, please specify tolerancetermination, and packaging codes: e.g. 1812FS-105KRC
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B impedance analyzer.
  3. Tolerances in bold are stocked for immediate shipment.
  4. Q measured at 1 MHz on an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
  5. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
  6. Isat: DC current at which the inductance drops 10% (typ.) from its value without current.
    Temperature derating curves.
  7. DCR measured on a micro-ohmmeter and a Coilcraft CCF840 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
  8. Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.


  • = 5%, K = 10% (Table above shows stock tolerances in bold.)


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


  • C = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel).
  • 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.
