Overview
The KEMET SCT39XV-400-Y2R0B003JH is a four-line common mode choke designed for high-current applications. It features an inductance of 67 µH at 100 kHz and supports a maximum DC current of 40 A. The component has a typical DC resistance of 0.53 mOhms and is rated for 1000 V. It complies with the AEC-Q200 automotive qualification standard, ensuring reliability under demanding conditions.
Feature Summary
- Four-line configuration for multi-phase noise suppression
- AEC-Q200 qualified for automotive reliability
- High current handling capability up to 40 A
- Low DC resistance for efficient power transmission
Applications
- Automotive power distribution systems
- Multi-phase motor drive circuits
- On-board charger (OBC) input filtering
- DC-DC converter EMI suppression
Procurement Notes
Verify the specific suffix Y2R0B003JH matches the required 67 µH inductance and 40 A rating. Confirm AEC-Q200 compliance is mandatory for the target application. Ensure the 1000 V rating aligns with system voltage requirements. Check package dimensions against PCB layout constraints before ordering.
Selection Notes
Select this component when four independent lines require simultaneous common mode noise reduction. The 40 A current rating suits high-power automotive or industrial converters. Consider the low DCR for minimizing thermal rise. Verify that the 67 µH value provides adequate attenuation at the switching frequency of the application.
Part Context
This part belongs to the KEMET SCT-XV series of common mode chokes. The series is engineered for robust performance in electric vehicle and renewable energy systems. The XV designation typically indicates enhanced thermal stability and higher voltage ratings compared to standard SCT models.
Replacement Considerations
Direct substitutes must match the 67 µH inductance, 40 A current rating, and four-line topology. Verify equivalent AEC-Q200 certification if used in automotive contexts. Cross-reference physical dimensions to ensure board compatibility without redesign.
