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.
