Notes
- When ordering, please specify termination and testing codes: e.g. ST450RAB105JLZ.
- Inductance at 2.5 MHz measured using an Agilent/HP 4286A or equivalent and a Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces. Inductance at 0.79 MHz measured using an Agilent/HP 4192A or equivalent and Coilcraft SMD-B test fixture.
- Q read at test frequency directly on an Agilent/HP 4395A impedance analyzer and an Agilent/HP 16193A test fixture or equivalents.
- SRF measured using an Agilent/HP 8753D network analyzer or equivalent and a Coilcraft SMD-D test fixture.
- DCR measured on a Cambridge Technology micro-ohmmeter or equivalent.
Termination:
