Overview
The KEMET SCF25XV-350-2R4A003JH is a two-line common mode choke from the SCF-XV series, designed for high-current applications. It features an inductance of 220 µH at 100 kHz and supports a maximum DC current of 35 A. The component has a low DC resistance of 0.7 mΩ and is rated for 1000 VAC. It utilizes nickel-zinc ferrite cores and is available in a through-hole package with dimensions of 25 mm height, 35 mm length, and 35 mm width. The device operates within a temperature range of -40 °C to +125 °C and holds AEC-Q200 qualification.
Feature Summary
- High current handling capability up to 35 A with low insertion loss
- AEC-Q200 qualified for automotive reliability standards
- Robust construction with nickel-zinc ferrite core material
- Through-hole mounting for secure PCB integration
Applications
- Automotive power supply filtering
- Electric vehicle (EV) charging systems
- Industrial motor drive noise suppression
- High-power DC-DC converter EMI reduction
Procurement Notes
Verify the specific suffix JH against official KEMET documentation to confirm packaging and tape-and-reel specifications. Ensure the voltage rating of 1000 VAC aligns with system requirements. Confirm that the 35 A current rating meets the peak load demands without saturation. Check for RoHS compliance status if required by regional regulations. Validate lead spacing and footprint dimensions against the target PCB layout before finalizing procurement.
Selection Notes
Select this component when high current capacity and automotive-grade reliability are required. The 220 µH inductance provides effective common mode noise attenuation at 100 kHz. The low DCR minimizes power loss in high-current paths. Consider the physical size constraints as the through-hole package is larger than surface-mount alternatives. Ensure the operating temperature range covers the intended environment extremes.
Part Context
This part belongs to the KEMET SCF-XV series of common mode chokes, which are engineered for demanding power electronics applications. The series is characterized by high saturation currents and robust thermal performance. The SCF25XV variant specifically targets automotive and industrial sectors where space efficiency and high current density are critical design parameters.
Replacement Considerations
Direct substitutes must match the 220 µH inductance, 35 A current rating, and 1000 VAC voltage rating. Verify that any alternative component also holds AEC-Q200 qualification if automotive use is intended. Compare physical dimensions to ensure compatibility with existing through-hole footprints. Check equivalent DCR values to maintain similar power loss characteristics.
