Notes
  1. When ordering, please specify termination and packaging codes: e.g. ME3215-104KLC
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A fixture in Agilent/HP 4284A impedance analyzer or equivalent.
  3. DCR measured at 25°C on a micro-ohmmeter and Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using Agilent/HP 8753D network analyzer and a Coilcraft SMD-D fixture. Details
  5. Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
  6. Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

  • L = RoHS compliant tin-silver-copper over tin over nickel over silver.
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (2000 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.
  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (7000 parts per full reel).
