Note 1.： All test data is referenced to 25℃ ambient.
Note 2.： Idc : DC current (A) that will cause an approximate
△T
of 40℃
Note 3.： Isat : DC current (A) that will cause Lo to drop approximately 30%
Note 4.： Operating Temperature Range -55℃ to + 125℃
Note 5.： The part temperature (ambient + temp rise ) should not exceed 125℃ under worse case
operating conditions. Circuit design , component placement, PWB trace size and thickness,
airflow and other cooling provision all affect the part temperature. Part temperature should be
verified in the end application.
Note 6.：
The rated current as listed is either the saturation current or the heating current
depending on which value is lower.
