Notes
- When ordering, please specify termination and testing codes: e.g. ST319RAD10NJLZ.
- Inductance measured at 500 MHz using a Coilcraft SMD-A fixture in an Agilent/HP4286 impedance analyzer with Coilcraft-provided correlation pieces.
- Q measured at 500 MHz using an Agilent/HP4291A with an Agilent/HP16193 test fixture.
- SRF measured using an Agilent/HP8753D network analyzer and a Coilcraft SMD -D test fixture.
- DCR measured on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture.
Termination:
- L = Silver-palladium-platinum glass frit.
- S = Tin-lead (63/37) over silver-palladium-platinum-glass frit. (Special Order, added cost)
- T = Tin-silver-copper (95.5/4/0.5) over silver-palladium-platinum-glass frit. (Special Order, added cost)
