per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
using a Coilcraft SMD-A fixture in an Agilent/
HP 4263B LCR meter or equivalent.
3. DCR measured on a micro-ohmmeter and a
Coilcraft CCF858 test fixture.
4. SRF measured using an Agilent/HP 8753D
network analyzer and a 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 25°C ambient.
7. Electrical specifications at 25°C.
