SCR39XV-220-2R3A012JH

Overview

The KEMET SCR39XV-220-2R3A012JH is a single-phase common mode choke designed for high-voltage applications. It features an inductance of 1.9 mH and supports a DC current rating of 22 A. The component has a maximum DC resistance of 3580 µohm and operates within a temperature range from -40°C to +125°C. Rated for 1000 V, this filter choke provides effective noise suppression in power circuits.

Feature Summary

• Single-phase configuration for common mode noise filtering
• High voltage rating suitable for demanding power environments
• Robust current handling capability with low DC resistance

Applications

• Industrial power supply filtering
• Motor drive noise suppression
• Inverter input/output stages

Procurement Notes

Verify the specific inductance value against official datasheets, as sources may list 1.6 mH or 1.9 mH. Confirm the operating temperature range and voltage rating match system requirements. Ensure the package type and mounting style are compatible with the intended PCB layout before finalizing procurement decisions.

Selection Notes

Select this component when single-phase common mode filtering is required at 1000 V. The 22 A current rating makes it suitable for medium-power industrial applications. Compare the 3580 µohm DC resistance against thermal management constraints. Ensure the 1.9 mH inductance meets the specific EMI attenuation needs of the circuit design.

Part Context

This part belongs to KEMET's SCR series of common mode chokes. These components are engineered for robust performance in harsh electrical environments. The series offers various inductance and current ratings to accommodate different power levels and filtering requirements across industrial and automotive sectors.

Replacement Considerations

The SCT39XV-220-2R3A012JH is an automotive-grade alternative with 1.07 mH inductance. Verify if the lower inductance meets EMI requirements. Check if AEC-Q200 qualification is necessary for the application.
