NOTE:
-
All test data is referenced to 25℃ ambient.
-
Irms: DC current(A) that will cause an approximate △T of 40℃.
-
Isat: DC current(A) that will cause Lo to drop approximate 30%.
-
Operating temperature range is -25℃ to 125℃.
-
The part temperature(ambient and 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.
