FN2090LL-10-08

Overview

The Schaffner FN2090LL-10-08 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It features threaded stud input and output terminations with an M4 thread specification. The component is rated for a continuous current of 10 A at 250 VAC. It operates within a frequency range of DC to 400 Hz and supports a maximum operating temperature of +100°C. The unit measures 113.5 mm in length, 57.5 mm in width, and 45.5 mm in height, weighing approximately 517 g. It complies with UL, CSA, and IEC/EN safety standards.

Feature Summary

• Two-stage architecture providing high differential and common-mode attenuation using high permeability core chokes
• Threaded stud terminals for secure mechanical and electrical connection
• Optimized performance for AC and DC applications within a compact form factor

Applications

• Power supplies requiring robust conducted noise suppression
• Battery charging systems
• Portable electronic devices with strict EMC requirements
• Energy-efficient industrial equipment

Procurement Notes

Verify the specific suffix 'LL' indicates threaded stud termination style distinct from other FN2090 variants. Confirm compliance with required regional safety certifications such as UL or CSA for the target market. Ensure chassis mounting holes align with the specified physical dimensions. Validate that the 10 A rating matches the system's continuous load requirements.

Selection Notes

Select this model when high attenuation is required in a compact space compared to standard series. The threaded stud interface suits applications needing vibration-resistant connections. Consider the LL variant specifically for its terminal configuration rather than screw or quick-connect options. Evaluate thermal management needs given the 100°C maximum operating temperature limit.

Part Context

This component belongs to the FN2090 series of multi-stage AC/DC EMI filters. The series offers various ratings from 1 to 30 A and includes optional medical (B type) or safety (A type) versions. The LL designation typically denotes a specific terminal style within the broader product family, focusing on enhanced performance through optimized inductance-to-amperage ratios.

Replacement Considerations

FN2090-10-08 serves as a related variant within the same series but may differ in terminal style or specific certification details. Verify that any substitute maintains the 10 A current rating and compatible mounting footprint.
