Notes:

1. Typical inductance occurs at I

and ET

values shown.

2. LI

/2 rating is the ability of the inductor to store energy.

3. Inductance is tested at 20kHz.

4. Design control test voltage is critical, inductance increases with voltage.

5. DCR for vertical part measured close to coil.

6. The part temperature (ambient temperature + temperature rise) should not exceed the upper limit of the operating

temperature 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.
