Notes
  1. When ordering, please specify termination and screening codes: e.g. ST336RAM223JRZ.
  2. Inductance measured at 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4286A impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
  3. Q measured on Agilent/HP 4291A with Agilent/HP 16197A test fixture or equivalents.
  4. SRF measured using Agilent/HP 8753ES network analyzer or equivalent with Coilcraft SMD-D test fixture.
  5. DCR measured on a Keithley 580 Micro-ohmmeter or equivalent with a Coilcraft CCF858 test fixture.

Termination:

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

Screening:

  • Z = Unscreened
  • = 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 options G or F.
