2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-A fixture in an Agilent/HP 4263B LCR meter.
3. Tolerances in bold are stocked for immediate shipment.
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.
