1. Inductance measured at 500 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
2. DCR measured on a Keithley 580 micro-ohmmeter or equivalent.
3. SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16193A 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.
6. Electrical specifications at 25°C.
Refer to Doc 362 âSoldering Surface Mount Componentsâ before soldering.
