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 microohmmeter or equivalent. 3. SRF measured using an Agilent/HP 8753D 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 a the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering. Caution: This series is not intended for use in high vibration or mechanical shock environments. We advise using additional means of securing the part to the circuit board to ensure its adhesion. Consider our SER2900 SER2900 series, which offers nearly identical electrical characteristics and incorporates a third mount pad for better stability and board adhesion.
