Notes
  1. When ordering, please specify termination and screening codes: e.g. ST214RAA75NJRZ.
  2. Inductance measured at 250 MHz using a Coilcraft SMD-F fixture in an Agilent/HP 4287 impedance analyzer with Coilcraft-provided correlation pieces.
  3. Q measured using an Agilent/HP 4991 with an Agilent/HP 16197 test fixture. Q min measured at 250 MHz.
  4. SRF measured using an Agilent/HP 8722ES network analyzer and a Coilcraft  CCF1235 test fixture.
  5. DCR measured on a micro-ohmmeter and a Coilcraft CCF1099 test fixture.

Termination:

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

Screening:

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