FN2090NN-6-06

Overview

The Schaffner FN2090NN-6-06 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 of 6 A. The component features Faston terminals and operates within a frequency range of 0 Hz to 400 Hz. Key electrical parameters include an inductance of 8 mH and a maximum leakage current of 14.5 mA. It functions reliably across a temperature range of -25°C to +100°C.

Feature Summary

• Two-stage filtering architecture providing high attenuation performance for noise suppression
• Utilizes high-permeability core material chokes for superior temperature stability
• Designed with a compact form factor compatible with existing FN2060 and FN2080 series footprints

Applications

• High-noise filtering applications requiring excellent attenuation
• Chassis-mounted power conditioning for electronic equipment
• Industrial control systems operating at 250 VAC

Procurement Notes

Verify the specific suffix 'NN' against the manufacturer's official datasheet to confirm terminal configuration and insulation ratings. Ensure the chassis mount style matches the enclosure design. Cross-reference the 8 mH inductance value with system requirements to validate filtering performance at the target frequencies.

Selection Notes

Select this model when a two-stage filter is required for significant noise reduction in single-phase AC/DC circuits. The 6 A rating suits moderate power loads. Consider the 14.5 mA leakage current limit for safety compliance. The chassis mount style dictates the mechanical integration method compared to flange or PCB options.
