SCF47B-400-1R8C040J

Overview

The KEMET SCF47B-400-1R8C040J is a three-phase common mode choke designed for AC line filtering applications. It features a nanocrystalline metal core to deliver ultra-high inductance and permeability. The component provides an inductance of 4 mH with a maximum DC current rating of 40 A. Its maximum DC resistance is specified at 2.1 mOhms. The device operates within a temperature range of -25°C to +120°C and utilizes through-hole vertical mounting with four pins.

Feature Summary

Utilizes nanocrystalline metal core technology for superior magnetic performance
Provides ultra-high inductance suitable for stringent EMI suppression requirements
Engineered for high current handling capabilities in three-phase power systems

Applications

Three-phase AC line filtering
Common mode noise suppression in industrial power supplies
EMI mitigation in motor drive circuits

Procurement Notes

Verify the specific suffix against official KEMET documentation to confirm pin configuration and tolerance variations. Ensure the ordering part number matches the required inductance and current ratings for your circuit design. Cross-reference datasheet revisions to confirm material compliance and package dimensions before finalizing procurement orders.

Selection Notes

Select this component when high permeability and compact size are required for three-phase noise reduction. The nanocrystalline core offers advantages over traditional ferrite cores in terms of saturation characteristics. Evaluate thermal management needs given the 120°C maximum operating temperature limit and the 40A current rating.

Part Context

This component belongs to the SCF-J/JH series of common mode chokes from KEMET. These filters are engineered for robust performance in demanding power electronics environments. The series emphasizes high inductance density and reliability for industrial and commercial power conversion applications.
