SCF25XV-350-2R4A003JV

Overview

The KEMET SCF25XV-350-2R4A003JV is a dual common mode choke from the SCF series, designed for high-voltage automotive applications. It features an inductance of 220 µH (0.22 mH) and supports a maximum current of 35 A with a DC resistance of 0.65 mΩ. Rated for 1000 V AC/DC, it operates within a temperature range of -40 °C to +125 °C. The component utilizes a vertical through-hole radial leaded package measuring 35 x 38.5 x 26.5 mm and holds AEC-Q200 qualification.

Feature Summary

• High voltage rating of 1000 VAC/DC suitable for demanding power environments
• AEC-Q200 qualified for automotive reliability standards
• Low DC resistance of 0.65 mΩ for efficient power transmission
• Vertical through-hole mounting style for robust mechanical connection

Applications

• Automotive power supply filtering
• High voltage DC-DC converter input/output stages
• Electric vehicle (EV) charging systems
• Industrial motor drive noise suppression

Procurement Notes

Verify the specific suffix codes against official KEMET documentation to ensure correct inductance and tolerance specifications. Confirm that the AEC-Q200 qualification aligns with your project's automotive reliability requirements. Check physical dimensions against your PCB footprint design to ensure compatibility with the 35 x 38.5 x 26.5 mm body size and radial lead spacing.

Selection Notes

Select this component when high current handling up to 35 A is required alongside significant common mode noise reduction. The 1000 V rating makes it suitable for isolated power stages where standard low-voltage chokes would fail. Ensure the operating environment stays within the -40 °C to +125 °C range. Consider the vertical form factor for board space constraints compared to horizontal alternatives.

Part Context

This part belongs to KEMET’s SCF series of common mode chokes, which are engineered for high-performance filtering in power electronics. The SCF25XV variant specifically targets high-voltage automotive and industrial markets. It complements lower-current or lower-voltage variants within the same family by offering enhanced power handling capabilities while maintaining compact vertical packaging for space-efficient designs.

Replacement Considerations

Consult official KEMET substitution guides for direct equivalents. Verify that any alternative maintains the 220 µH inductance, 35 A current rating, and 1000 V voltage rating. Ensure the replacement also meets AEC-Q200 standards if automotive compliance is mandatory. Physical dimensions and lead configurations must match to avoid PCB redesign.
