Notes
  1. When ordering, please specify tolerance, termination and screening codes: e.g. CP312RAQR47JRZ.
  2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP E4982A impedance analyzer with Coilcraft-provided correlation pieces.
  3. Tolerances in bold are stocked for immediate shipment.
  4. Q measured using an Agilent/HP4991A with an Agilent/HP16197 test fixture.
  5. SRF measured using an Agilent/HP 5071C/8722ES network analyzer and a Coilcraft CCF1052 test fixture.
  6. DCR measured on a micro-ohmmeter and a Coilcraft CCF1010/A test fixture.
  7. Maximum current that can be applied at 125°C.

Tolerance:

  • G = 2%
  • H = 3%
  • J = 5%
Table shows stock values and tolerances in bold.

Termination:

  • R = Matte tin over nickel over silver-platinum glass frit
  • P = Tin-lead (63/37) over 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

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.
