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.
