Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286 impedance analyzer or equivalent with Coilcraft-provided correla- tion pieces. 3. Q measured at the same frequency as inductance using an Agilent/ HP 4291A with an Agilent/HP 16193 test fixture or equivalents. 4. SRF measured using an Agilent/HP 8753ES network analyzer or equiva- lent and a Coilcraft SMD-D test fixture. 5. DCR measured on a micro-ohmmeter. 6. Electrical specifications at 25°C.
