All test data referenced to 25℃ ambient. 3. Testing Instrument : L: 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 1) will cause L0 to drop approximately 10%. Saturation Current (Isat 2) will cause L0 to drop approximately 20%. Saturation Current (Isat 3) 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. DCR Test 1625 1R0 Halogen-free Halogen 1. Soft saturation. 2. High current，low DCR，high efficiency. 3. Very low acoustic noise and very low leakage flux noise. 4. High reliability. 5. 100% Lead(Pb)-Free and RoHS compliant. 6. Operating temperature -40~+125℃(Including self - temperature rise)
