FN2090-6-08

Overview

The Schaffner FN2090-6-08 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports a rated current of 6 A and operates at voltages up to 250 VAC. The component utilizes faston terminals for connection and functions within a frequency range of 0 Hz to 400 Hz. Certified under UL, CSA, and IEC/EN standards, it features a compact form factor with dimensions of 94 mm in length, 56 mm in width, and 45.4 mm in height. The unit weighs approximately 530 g and operates reliably between -25°C and +100°C.

Feature Summary

• Two-stage architecture providing high differential and common-mode attenuation
• Chassis mount design optimized for easy and fast installation
• High permeability core material chokes for superior thermal behavior
• Compatible with noisy applications requiring excellent conducted noise suppression

Applications

• Industrial equipment power conditioning
• Medical device power supplies
• General purpose AC/DC power filtering
• Electronic systems requiring strict EMI compliance

Procurement Notes

Verify the specific terminal type and current rating against the datasheet before integration. Confirm that the chassis mounting holes align with the enclosure design. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for any optional surge protection or medical certification variants if applicable to the specific system constraints.

Selection Notes

Select this model when a compact, two-stage filter is required for 6 A single-phase applications. The FN2090 series offers higher inductance per ampere compared to older FN2060 and FN2080 series models within the same footprint. Consider the Z-type variant if overvoltage protection is needed, or the B-type for medical leakage current limits.

Part Context

The FN2090 series represents an enhanced generation of Schaffner EMI filters, offering improved performance indicators over previous generations. It maintains the same physical dimensions as the FN2060 and FN2080 series, allowing for direct mechanical upgrades in existing designs while delivering better attenuation characteristics through advanced core materials.

Replacement Considerations

FN2090-6-06 serves as a functional alternative within the same series, differing primarily in terminal configuration.
