Notes
- When ordering, specify tolerance, termination and screening codes: e.g. ST450RAA333JRZ.
- Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286 impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
- Q measured at the same frequency as inductance using an Agilent/ HP 4291A with an Agilent/HP 16193 test fixture or equivalents.
- SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft SMD-D test fixture.
- DCR measured on a micro-ohmmeter.
Tolerance:
- G = 2%
- J = 5%
Termination:
- R = Matte tin over nickel over silver-platinum glass frit
- L = Silver-palladium-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.
- S = Tin-lead (63/37) over silver-platinum-glass frit.
- T = Tin-silver-copper (95.5/4/0.5) 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.
