FN2090A-8-06

Overview

The Schaffner FN2090A-8-06 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It features a rated current of 8 A and a voltage rating of 250 VAC. The component utilizes faston terminals for connection and operates within a frequency range of 0 Hz to 400 Hz. Certified under UL, CSA, and IEC/EN standards, this filter belongs to the FN2090 series, which offers high differential and common-mode attenuation using chokes with high permeable core material.

Feature Summary

• Two-stage architecture providing excellent conducted attenuation performance
• Chassis mount design with metal case for optimal earth connection
• Faston terminal style for easy and fast installation

Applications

• Medical equipment requiring low leakage currents
• Safety-critical industrial applications
• General purpose AC/DC power filtering

Procurement Notes

Verify the specific suffix 'A' confirms the safety version with low capacitance requirements. Confirm chassis mounting dimensions and faston terminal pitch match the target PCB or busbar layout. Ensure the 8 A continuous current rating aligns with the system's maximum load. Check for required regulatory certifications such as UL or IEC for the final assembly.

Selection Notes

Select this model when low leakage current is critical for safety compliance. The 'A' designation indicates a variant optimized for safety-critical applications compared to standard versions. Consider the chassis mounting requirement and available panel space. Evaluate if the two-stage attenuation meets the specific EMI noise environment requirements.

Part Context

This component is part of the Schaffner FN2090 series, which includes multi-stage AC/DC EMI filters rated from 1 to 30 A. The series offers optional medical (B type), safety (A type), and enhanced performance versions. The FN2090 series is distinguished by higher inductivity versus amperage, providing increased attenuation in a compact form factor compared to earlier generations like the FN2060.
