2. Inductance measured at 250 MHz using a Coilcraft SMD-F fixture in
an Agilent/HP 4286A impedance analyzer or equivalent with Coilcraftprovided correlation pieces.
3. Q measured 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
equivalent and a Coilcraft CCF1232 test fixture.
5. DCR measured on a Keithley 580 micro-ohmmeter and a Coilcraft
CCF1192 test fixture.
6. Electrical specifications at 25°C.
