2. 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.
3. Q read at test frequency directly on an Agilent/HP 4192A LF impedance
analyzer and a Coilcraft SMD-B test fixture.
4. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. DCR measured on a Cambridge Technology micro-ohmmeter.
6. Electrical specifications at 25°C.
