FN2640-20-05-C11

Overview

The Schaffner FN2640-20-05-C11 is a single-phase, low-profile IEC inlet EMC/EMI filter designed for high-performance noise suppression. It features a 20 A current rating and operates at 250 VAC. The unit utilizes an IEC C20 inlet interface with screw terminals for secure connection. Key electrical parameters include a maximum leakage current of 370 µA and a common-mode capacitance of 4.7 nF. Designed for frequencies from 0 Hz to 60 Hz, it offers robust attenuation in a compact form factor suitable for space-constrained installations.

Feature Summary

• Low-profile design optimized for dense mounting environments
• High-performance EMI/EMC filtering capabilities
• Robust construction for reliable operation

Applications

• Robotics systems
• Data center infrastructure
• 19-inch rack mounted equipment

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure correct terminal configuration and certification requirements. Confirm that the 20 A rating aligns with the system's continuous load needs. Check for regional compliance markings required for the target market installation.

Selection Notes

Select this model when space constraints require a low-profile form factor alongside high current handling. Ensure the IEC C20 inlet matches the downstream power cord or connector type. Validate that the 4.7 nF capacitance does not exceed local safety standards for leakage current limits in sensitive medical or precision applications.

Part Context

This component belongs to the FN2640 series, which provides a range of dedicated single-phase filters. The series is engineered to meet stringent EMC standards while maintaining a small footprint. It serves as a critical interface between the AC power source and sensitive electronic loads, ensuring signal integrity and regulatory compliance.

Replacement Considerations

Cross-reference with other FN2640 variants for different current ratings if the 20 A specification is insufficient. Verify mechanical compatibility with existing panel cutouts and mounting hardware before substituting.
