1.All test data is referenced to 25 °C ambient
2.Operating temperature range -55 °C to +125°C
3.Irms (A):DC current (A) that will cause an MPIF proximate ΔT of 40°C(reference ambient temperature is 25°C)
4.Isat(A):DC current (A) that will cause L0 to drop MPIF proximately 30%
5.The part temperature (ambient + temp rise) should not exceed 125°C under worst case operating conditions.Circuit design, component placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end MPIF plication.
6.Absolute maximum voltage 30VDC
