Testing Instrument : L/Q: HP4284A,HP4395A,CH11025,CH3302,CH1320 ,CH1320S LCR METER / Rdc:CH16502,Agilent33420A MICRO OHMMETER,or EQU. 4. Current that causes the specified temperature rise from 25°C ambient. 5. Saturation Current (Isat) will cause L0 to drop approximately 30%. 6. The part temperature (ambient + temp rise) should not exceed 125℃under worst case operating conditions.Circuit design,component,PCB trace size and thickness,airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application. 7. Special inquiries besides the above common used types can be met on your requirement. 8. Rated operating voltage(across inductor) 40V ref.
