MR-2043

Power Line Filter Modules Overview

The KEMET MR-2043 is a single-phase EMI/RFI power line filter designed for general-purpose noise suppression. It features a rated voltage of 250 VAC and a current rating of 4 A. The unit incorporates a 1-stage filtering architecture with an inrush current limit of 300 mOhms. Designed for chassis mounting, it utilizes Faston terminals for electrical connection. Key specifications include a leakage current of 0.75 mA and compliance with standard EMC requirements for electronic equipment.

Power Line Filter Modules Feature Summary

• Single-phase EMI/RFI noise suppression for AC power lines
• Chassis mount construction for secure installation
• Faston terminal interface for simplified wiring
• Integrated inrush current limiting capability

Power Line Filter Modules Applications

• General purpose electronic equipment power input stages
• Industrial control systems requiring single-phase filtering
• Medical devices adhering to leakage current standards
• Office automation equipment power supplies

Power Line Filter Modules Procurement Notes

Verify the specific datasheet revision to confirm terminal pitch dimensions and mounting hole patterns prior to integration. Ensure the operating environment temperature remains within the specified range for optimal performance. Confirm that the 4 A continuous current rating aligns with the load requirements. Check for any regional regulatory certifications required for the target market. Validate that the 250 VAC rating exceeds the maximum system voltage.

Power Line Filter Modules Selection Notes

Select this component when single-stage attenuation is sufficient for the application's EMI profile. The 4 A rating suits moderate power loads without excessive size constraints. Consider the Faston termination style if PCB space is limited or through-hole mounting is preferred. Evaluate the 300 mOhms inrush limit against capacitor charging demands. Compare leakage current limits against safety standards for personnel protection.

Power Line Filter Modules Part Context

The MR series represents KEMET's line of single-phase EMI filters. These components are engineered for compact noise suppression in AC power applications. The MR-2043 specifically targets general-purpose markets where cost-effective shielding is required. It complements larger three-phase units by providing a solution for lower current single-phase circuits.

Power Line Filter Modules Replacement Considerations

Cross-reference with MA-2043 for dimensional compatibility checks. Verify that substitute parts maintain the 4 A current rating and 250 VAC voltage class. Ensure replacement filters offer equivalent leakage current specifications. Confirm terminal type matches existing harnesses or PCB layouts.
