Test Remarks:
- (1). All test data is referenced to 25 ambient.
- (2). Irms: DC current that causes the temperature rise (T 40) from 25 ambient.
4. General Specifications
- (1). Operating Temperature: -40 ~ +125 (Including self-generated heat).
- (2). Storage Temperature: -10 ~ +40 R.H.: 60% Max.
- (3). Moisture Sensitivity Level (MSL): 1
- (4). Recommended products should be used within 12 months from the date of delivery.
- (5). The part temperature (ambient + temp rise) should not exceed 125 C 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.
