Notes
- When ordering, please specify termination code: e.g. ML450RAB105JLZ.
- Inductance at 2.5 MHz measured using an Agilent/HP 4286A and a Coilcraft SMD-A fixture with Coilcraft- provided correlation pieces. Inductance at 0.79 MHz measured using an Agilent/HP 4192A and Coilcraft SMD-B test fixture.
- Q read at test frequency directly on an Agilent/HP 4192A LF impedance analyzer and a Coilcraft SMD-B test fixture.
- SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
- DCR measured on a Cambridge Technology micro-ohmmeter.
Termination:
- L = Silver-palladium-platinum glass frit.
- R = Tin over nickel over silver-platinum-glass frit. (Special order, added cost)
