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 10ꢀ  
(max) from its value without current.  
6. Current that causes the specified temperature rise  
from 25°C ambient.  
7. Electrical specifications at 25°C.  
Refer to Doc 362 “Soldering Surface Mount  
Components” before soldering.
