FN2090-6-06

Overview

The Schaffner FN2090-6-06 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It features a rated voltage of 250 VAC and a current rating of 6 A. The unit operates within a frequency range of 0 Hz to 400 Hz and utilizes fast-on terminals for connection. Key electrical specifications include a leakage current of 610 uA and an operating temperature range from -25°C to +100°C. Physical dimensions are 64.8 mm in length, 49.8 mm in width, and 30.3 mm in height, with a weight of 191 g. It holds UL, CSA, and IEC/EN certifications.

Feature Summary

• Two-stage architecture providing high differential and common-mode attenuation using high permeability core material chokes.
• Compact form factor compatible with existing FN 2060 and FN 2080 series mounting requirements.
• Designed for noisy applications requiring excellent conducted noise suppression performance.
• UL94V-2 flame retardant rating suitable for industrial and general electronic equipment.

Applications

• Industrial machinery power supply filtering
• Medical equipment noise suppression
• General electronic equipment EMI reduction
• Fax and imaging device power lines

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm terminal type and certification status. Ensure the chassis mounting hole pattern matches the design enclosure. Confirm that the 6 A current rating and 610 uA leakage current meet system safety and thermal requirements. Cross-reference the official TE Connectivity / Schaffner documentation for any recent compliance updates or pinout variations.

Selection Notes

Select this component when a two-stage filter is required for single-phase AC or DC lines up to 400 Hz. The 6 A rating suits moderate power applications. Consider the FN2090B variant if medical isolation without Y-capacitors is needed. Verify that the fast-on terminal style aligns with available connector hardware. Ensure the physical footprint fits the designated chassis space alongside other components.

Part Context

This part belongs to the Schaffner FN2090 series, which offers optimized filter ranges for enhanced performance in both AC and DC applications. The series maintains a consistent compact size across different current ratings, allowing designers to scale filtering capabilities without changing the mechanical layout. It serves as an upgrade path from the FN2060 and FN2080 series due to higher inductance-to-amperage ratios.

Replacement Considerations

Publicly confirmed substitute part numbers for FN2090-6-06 were not identified in the provided source material. Designers should consult the manufacturer's selection guide for direct equivalents within the FN2090 family or verify compatibility with alternative brands based on identical electrical and mechanical parameters.
