All test data is referenced to 25
Test Condition:1MHz, 1.0Vrms
Idc : DC current (A) that will cause an approximate
T of 40
Isat : DC current (A) that will cause Lo to drop approximately 30%
Operating Temperature Range -55
to + 125
The part temperature (ambient + temp rise ) should not exceed 125
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 7.
The rated current as listed is either the saturation current or the heating current depending on which
value is lower.
