SCF47X-200-S1R8B011JH

Overview

The KEMET SCF47X-200-S1R8B011JH is a three-phase common mode choke designed for high-power applications. It features an inductance of 3.21 mH and supports a maximum DC current of 20 A. The component has a maximum DC resistance of 2100 µohms (2.1 mohms) and operates within a temperature range of -40°C to +130°C. Rated for 600V, it utilizes a vertical through-hole mounting style.

Feature Summary

• Three-phase configuration for balanced noise suppression
• High thermal stability with extended operating temperature range
• Low impedance design for efficient power transmission

Applications

• Industrial motor drives
• Power conversion systems
• Three-phase AC/DC converters

Procurement Notes

Verify the specific voltage rating and phase configuration against the official datasheet before integration. Confirm that the 20A current rating aligns with the system's peak load requirements. Ensure the vertical through-hole footprint matches the PCB layout constraints. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when three-phase noise filtering is required at 20A levels. The 3.21 mH inductance provides significant common-mode attenuation. Consider the 2100 µohm DCR impact on system efficiency. The wide temperature range suits harsh industrial environments where standard components may fail.

Part Context

This part belongs to the KEMET SCF47X series of common mode chokes. The series is characterized by high current handling capabilities and robust construction for industrial power electronics. The 'X' suffix typically denotes specific core material or construction variations within the broader SCF family.

Replacement Considerations

Direct substitutes must match the 3.21 mH inductance, 20A current rating, and three-phase topology. Verify physical dimensions for board compatibility. Cross-reference with other KEMET SCF models or competitors offering similar three-phase specifications.
