| Characteristics | Description |
|---|---|
| Ambient Temperature | All test data is based on 25 ambient. |
| Isat Definition | DC current(A) that will cause an approximate T 40 |
| Irms Definition | DC current(A) that will cause L0 to drop approximately 30% Typ |
| Operating Temperature Range | -55~+125 |
| Part Temperature Limit | The part temperature (ambient + temp rise) should not exceed 125 under worst case operating conditions. Circuit design, component, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the application. |
