5. Rated current, Irms: 4A.
6. Operating temperature range: -40°C to +85°C.
7. 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.
