2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286 impedance analyzer or equivalent with Coilcraft-provided correla-
tion pieces.

thick, 8 mm pocket spacing, 3.7 mm pocket depth
3. Q measured at the same frequency as inductance using an Agilent/
HP 4291A with an Agilent/HP 16197 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 Keithley 580 micro-ohmmeter or equivalent and a
Coilcraft CCF859 test fixture.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
