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,
0.118 0.01
component placement, PWB trace size and thickness, airflow
[3.0 0.3]
and other cooling provisions all affect the part temperature. Part
temperature should be verified in the end application 0.453 [11.5]
Rated operating voltage (across inductor) = 50 V max.
