Notes

Inductance measured at 2.5 MHz using Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
Q measured at 2.5 MHz using an Agilent/HP 4291A with an Agilent/HP 16197 test fixture or equivalents.
SRF measured using an Agilent/HP 8753ES network analyzer or equivalent with a Coilcraft SMD-D fixture.
DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a Coilcraft CCF858 test fixture.
