FN2090A-4-06

Overview

The Schaffner FN2090A-4-06 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports a rated voltage of 250 VAC and a continuous current rating of 4 A. The component operates within a frequency range of 0 Hz to 400 Hz and utilizes Faston quick-connect terminals for circuit integration. Key electrical parameters include a leakage current of 140 µA and compliance with UL, CSA, and IEC/EN standards.

Feature Summary

• Two-stage attenuation architecture for enhanced noise suppression
• Metal enclosure ensures optimal earth connection and high-frequency performance
• Faston terminal interface facilitates rapid circuit board installation

Applications

• Medical equipment power input stages
• Industrial control systems requiring EMC compliance
• General purpose electronic devices needing EMI protection

Procurement Notes

Verify the specific suffix code against official TE Connectivity / Schaffner documentation to confirm terminal type and certification status. Ensure the selected variant matches the required chassis mounting configuration and current rating for the target application environment.

Selection Notes

Select this model when a compact, single-phase solution is required for low-current applications up to 4 A. The two-stage design offers superior attenuation compared to single-stage alternatives. Confirm that the Faston terminal style aligns with the available PCB header or wire termination options in the system design.

Part Context

This component belongs to the FN2090 series, which features metal cases for improved grounding and space for multiple circuit stages. The series is engineered for effective noise attenuation in sensitive electronic environments while maintaining robust mechanical stability through chassis mounting.

Replacement Considerations

Consult official substitution guides for equivalent ratings. Verify that any alternative maintains the same two-stage topology, Faston terminal style, and certified safety approvals for direct replacement.
