Operating Conditions and Notes
- Operating Temperature: -55C ~ 125C (Including self-temperature rise)
- Storage Temperature: -20C to +40C; 75% RH max.
- Standard Testing Conditions: Temperature (15 to 35), Humidity (25 to 85% RH)
- Absolute maximum voltage: 30VDC (should be verified in the end application)
- Isat: Inductance drop 30% from its value without current.
- Irms: For a 40C temperature rise from 25C ambient.
- The part temperature (ambient + temp rise) should not exceed 125C under worst-case operating conditions.
- Moisture Sensitivity Level (MSL): Level 1.
