Overview
The KEMET SCF25XV-310-2R3A004JH is a common mode choke from the SCF-XV series, designed for high-current applications. It features an inductance of 400 µH and a maximum DC resistance of 1000 µΩ. The component supports a rated DC current of 31 A and operates within a temperature range of -40°C to +125°C. It holds AEC-Q200 automotive qualification and includes certifications such as UL, ENEC, cUL, and CQC.
Feature Summary
- Automotive-grade reliability certified under AEC-Q200 standards
- High current handling capability with low DC resistance
- Robust construction using nickel-zinc ferrite core material
Applications
- Electromagnetic interference suppression in automotive electronics
- Power supply input filtering for high-current circuits
- Common mode noise reduction in industrial power systems
Procurement Notes
Verify the specific suffix (JH vs JV) against official KEMET documentation to confirm exact electrical tolerances and packaging details. Ensure the procurement channel provides valid traceability for AEC-Q200 qualified components. Confirm that the delivered units match the specified 400 µH inductance and 31 A current rating through incoming inspection or supplier certificates.
Selection Notes
Select this component when designing circuits requiring high current capacity alongside effective common mode noise filtration. The low DC resistance minimizes power loss in high-amperage paths. Verify that the operating environment falls within the specified -40°C to +125°C range. Consider the physical dimensions and lead spacing to ensure compatibility with the target PCB layout and mechanical constraints.
Part Context
This part belongs to the KEMET SCF-XV series of common mode chokes, which are engineered for demanding automotive and industrial environments. The series emphasizes high saturation current and robust thermal performance. The SCF25XV variant specifically targets applications requiring significant current handling while maintaining compact form factors suitable for modern electronic assemblies.
Replacement Considerations
The SCF25XV-310-2R3A004JV is a documented alternative within the same series. Verify that the JV suffix does not alter critical parameters such as inductance tolerance or packaging before substitution.
