Inductance Tolerance 20%
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 20%
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.
