| Ambient Temperature | All test data is based on 25 ambient. |
| Temperature Rise (T) | Caused by DC current (A) that will cause an approximate T 40. |
| Inductance Drop | DC current (A) that will cause L0 to drop approximately 10% Typ. |
| Operating Temperature Range | -55 ~ +125 |
| Part Temperature Limit | Should not exceed 125 under worst-case operating conditions (ambient + temp rise). Factors affecting part temperature include circuit design, component, PWB trace size and thickness, airflow, and other cooling provisions. Part temperature should be verified in the actual application. |
