Notes
- When ordering, specify tolerance, termination, and screening codes: e.g. CP235RAK56NJRZ.
- Inductance measured at 250 MHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A fixture in Agilent/HP 4287A impedance analyzer.
- Tolerances in bold are stocked for immediate shipment.
- Q is measured using Agilent/HP4991A with Agilent/HP 16197 test fixture.
- SRF is measured on an Agilent 8753ES (or equivalent) with a Coilcraft CCF1232 test fixture.
- DCR is measured on a Keithly 580 micro-ohmmeter (or equivalent) with a Coilcraft CCF1010 test fixture.
Tolerance:
- G = 2%
- H = 3%
- J = 5%
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 options G or F.
