Notes
  1. When ordering, please specify termination and packaging codes: e.g. HA4031-ALC
  2. Inductance measured at 50 MHz, using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
  3. Q measured measured at 50 MHz, using an Agilent/HP 4291A with an Agilent/HP 16193 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 and a Coilcraft CCF859 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
  6. Current that causes a 15°C temperature rise from 25°C ambient.

Termination:

  • L = RoHS compliant silver-palladium-platinum-glass frit.
  • R = RoHS compliant matte tin over nickel over silver platinum-glass frit.
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)
  • T = RoHS tin-silver-copper (95.5/4/0.5) (Special order, added cost)
  • P = non-RoHS tin-lead (63/37) over matte tin over nickel over silver-platinum-glass frit. (Special order, added cost)
  • Q = RoHS tin-silver-copper (95.5/4/0.5) over matte tin over nickel over silver-platinum-glass frit. (Special order, added cost)

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (600 parts per full reel).
  • B = Less than full reel
    In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
  • D = 13" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel).
