SCR29XV-250-2R2A008JV

Overview

The KEMET SCR29XV-250-2R2A008JV is a vertical through-hole common mode choke designed for high-current applications. It features an inductance of 390 µH at 100 kHz and supports a DC current rating of 25 A. The component has a maximum DC resistance of 1.68 mΩ and withstands up to 1000 VAC insulation voltage. Certified under AEC-Q200, it operates within a temperature range of -40°C to +125°C. Physical dimensions are approximately 21.9 mm x 38.7 mm x 41.5 mm.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High current handling capability of 25 Amperes
• Low DC resistance for efficient power transmission
• Vertical leaded package for robust mechanical mounting

Applications

• Automotive power distribution networks
• Electric vehicle charging systems
• Industrial motor drive circuits
• High-power DC-DC converter input filtering

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout and tolerance specifications. Ensure the procurement channel provides traceability documentation required for AEC-Q200 certified components. Confirm that storage conditions comply with moisture sensitivity levels if applicable. Cross-reference the part number with official KEMET catalogs to avoid counterfeit substitutes.

Selection Notes

Select this component when high current capacity and low impedance are critical for noise suppression in power lines. The 390 µH inductance offers effective common mode noise attenuation without excessive saturation risks at 25 A. Consider the vertical form factor for board space constraints requiring height rather than footprint expansion. Validate thermal performance under continuous load to ensure the 125°C operating limit is not exceeded.

Part Context

This part belongs to KEMET’s SCR29XV series of high-performance common mode chokes. The series is engineered for demanding environments where stability under high current and voltage stress is essential. It complements other EMI filtering solutions by providing robust suppression in compact through-hole packages suitable for heavy-duty industrial and automotive infrastructure.

Replacement Considerations

Direct substitutes include parts from the same SCR29XV family with adjusted inductance or current ratings. Verify compatibility with existing PCB hole patterns and terminal spacing. Ensure replacement units maintain the same AEC-Q200 certification and voltage isolation characteristics.
