2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc us-
ing Coilcraft SMD -A fixture in Agilent/HP 4284A imped -
ance analyzer.
3. DCR measured on a micro-ohmmeter and Coilcraft
CCF858 test fixture.
4. SRF measured using Agilent/HP 8753D network ana-
lyzer and Coilcraft SMD -D test fixture.
5. DC current at which the inductance drops the specified
amount from its value without current.
6. Current that causes the specified temperature rise from
25C ambient.
7. Electrical specifications at 25C.
