Notes
  1. When ordering, please specify termination and screening codes: e.g. ST145RAN7N1JRZ.
  2. Inductance measured at 25 MHz using a Coilcraft SMD-F fixture in
    an Agilent/HP 4286 impedance analyzer or equivalent with Coilcraftprovided
    correlation pieces.
  3. Q measured using an Agilent/HP 4291A with an Agilent/HP 16197A
    test fixture or equivalents.
  4. SRF is measured on an Agilent 8753ES (or equivalent) with a Coilcraft
    CCF1235 test fixture.
  5. DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent)
    with a Coilcraft CCF1099 test fixture.

Termination:

  • R = Matte tin over nickel over silver-platinum glass frit.
  • P = Tin-lead (63/37) over tin over nickel over silverplatinum-glass frit.
  • Q= Tin-silver-copper (95.5/4/0.5) over tin over nickel over silver-platinum-glass frit.

Screening:

  • Z = Unscreened
  • H = Coilcraft CP-SA-10001 Group A
    • Screening performed to the document’s latest revision.
    • Lot qualification (Group B) available.
    • Custom testing also available.
    • Country of origin restrictions available; prefix option G.
