FN2090LL-16-06

Overview

The Schaffner FN2090LL-16-06 is a single-phase, two-stage power line filter designed for chassis mounting. It features a rated voltage of 250 VAC and a current rating of 16 A. The unit operates within a frequency range of DC to 400 Hz and utilizes faston terminals for connection. Physical dimensions are 94 mm in length, 56 mm in width, and 45.4 mm in height. It includes surge pulse protection and complies with UL, CSA, and IEC/EN standards.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• Integrated surge pulse protection capability
• Optimized design for noisy applications requiring excellent conducted emission performance
• Chassis mount configuration with faston terminal options

Applications

• Industrial equipment requiring robust EMI suppression
• Medical devices utilizing B-type or A-type filter variants
• Power supplies and AC/DC converters
• General purpose electronic systems with strict EMC requirements

Procurement Notes

Verify the specific suffix against official datasheets to confirm terminal type and insulation class. Confirm compliance certifications required for the target market. Ensure chassis mounting hardware matches the specified dimensions. Validate thermal derating curves for the intended operating environment.

Selection Notes

Select this model for applications demanding high attenuation in a compact form factor. The LL variant offers enhanced performance compared to standard series. Consider leakage current limits if used in safety-critical medical environments. Verify that the 16 A rating aligns with peak load requirements.

Part Context

This component belongs to the FN2090 series, which provides optimized filter ranges for AC and DC applications. The series is characterized by high permeability core materials and excellent thermal behavior. It serves as an upgrade path from previous generations like the FN2060 and FN2080 for improved noise reduction.

Replacement Considerations

Direct substitutes include other FN2090 series variants with matching current ratings. Cross-reference with FN2070B series for lower current needs. Verify mechanical footprint compatibility before replacing existing designs.
