DC current (A) that will cause an approximate T of 40 °C
DC current (A) that will cause L0 to drop approximately 20 %
The part temperature (ambient + temp. rise) should not exceed
125 °C under worst case operating conditions. Circuit design,
component placement, PWB trace size and thickness, airflow
and other cooling provisions all affect the part temperature. Part
temperature should be verified in the end application.
