Notes
- When ordering, please specify termination and screening codes: e.g. ST145RAN7N1JRZ.
- Inductance measured at 25 MHz using a Coilcraft SMD-F fixture in
an Agilent/HP 4286 impedance analyzer or equivalent with Coilcraftprovided
correlation pieces. - Q measured using an Agilent/HP 4291A with an Agilent/HP 16197A
test fixture or equivalents. - SRF is measured on an Agilent 8753ES (or equivalent) with a Coilcraft
CCF1235 test fixture. - DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent)
with a Coilcraft CCF1099 test fixture.
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 option G.
