MR-2021

Power Line Filter Modules Overview

The KEMET MR-2021 is a single-stage power line filter designed for electromagnetic interference suppression. It features a rated voltage of 250 VAC and 250 VDC with a current rating of 2 A. The unit has a leakage current of 0.75 mA and operates within a temperature range of -20°C to +60°C. Constructed in a plastic box, it measures 49 mm in length and 27 mm in height. The component supports chassis mounting and utilizes Faston terminals for electrical connection.

Power Line Filter Modules Feature Summary

• Single-stage noise filtering configuration
• Chassis mount installation style
• Faston terminal interface

Power Line Filter Modules Applications

• General purpose power line filtering
• Electromagnetic compatibility (EMC) suppression
• Radio frequency interference (RFI) reduction

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version to confirm compliance with UL, CSA, and TUV approvals. Ensure the operating environment remains within the specified -20°C to +60°C temperature range. Confirm that the 2 A current rating and 250 VAC/VDC voltage limits align with the target circuit requirements before integration.

Power Line Filter Modules Selection Notes

Select this component when a single-stage solution is sufficient for EMI/RFI mitigation in low-current applications. The chassis mount design requires adequate panel space for the 49 x 27 mm footprint. Verify that Faston terminals are compatible with the mating connectors in the assembly design.

Power Line Filter Modules Part Context

This part belongs to KEMET's power line filter series, specifically engineered for general-purpose noise suppression. It serves as an EMC/EMI filter module intended for integration into equipment requiring radio frequency interference reduction. The plastic box construction provides insulation while maintaining a compact profile for standard chassis installations.

Power Line Filter Modules Replacement Considerations

Consult official KEMET documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' filters without verifying electrical ratings and mechanical dimensions.
