Notes
• All test data is referenced to 25 °C ambient
• Operating temperature range -55 °C to +125 °C
• 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.
• Rated operating voltage (across inductor) = 40 V
