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. SRF measured using an Agilent/HP 8753D network
analyzer and a Coilcraft SMD-D test fixture.
4. DC current at which the inductance drops the specified
amount from its value without current.
5. Current that causes the specified temperature rise from
25°C ambient.
