2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-A fixture in an Agilent/HP 4263B impedance analyzer.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 1 MHz on an Agilent/HP 4291A with an Agilent/HP 16193
test fixture.
5. DCR measured on a micro-ohmmeter and a Coilcraft CCF840 test
fixture.
6. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
7. DC current at which the inductance drops 10% (typ) from its value
without current.
8. Current that causes a 40°C temperature rise from 25°C ambient.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
