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 25°C that causes the specified
inductance drop from its value without current.
Click for temperature derating information..
6. Current that causes the specified temperature rise
from 25°C ambient.This information is for reference
only and does not represent absolute maximum
ratings. Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount
Components” before soldering.
