FN2090-3-06

Overview

The Schaffner FN2090-3-06 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports a maximum current of 3 A and operates at voltages up to 250 V AC/DC within a frequency range of 0 Hz to 400 Hz. Key electrical parameters include a capacitance value of 330 nF, an inductance of 14 mH, and a leakage current of 0.5 mA. The unit features fast-on terminals and includes a 470 kΩ resistor. It functions reliably between -25°C and +100°C, with physical dimensions of 54 mm length, 85 mm depth, and 30.3 mm height.

Feature Summary

• Two-stage filtering architecture provides high attenuation performance for electromagnetic interference suppression.
• Designed for direct chassis installation using fast-on terminal connections for simplified integration.
• Operates effectively across a wide temperature range from -25°C to +100°C.

Applications

• Single-phase AC/DC power line filtering
• Chassis-mounted electronic equipment protection
• Industrial control systems requiring EMI suppression

Procurement Notes

Verify the specific manufacturer designation, as TE Connectivity and Schaffner EMC Inc. are associated with this part number. Confirm that the fast-on terminal style matches your wiring requirements. Ensure the chassis mounting configuration aligns with your enclosure design. Check for updated compliance certifications such as UL, CSA, or IEC/EN if required for your target market. Validate the operating temperature range against your environmental conditions.

Selection Notes

Select this model when a single-phase, two-stage filter is required for currents up to 3 A. The chassis mount style is suitable for applications where panel integration is preferred over PCB mounting. Consider the 330 nF capacitance and 14 mH inductance values for your specific noise profile. Ensure the 250 V AC/DC rating meets your system voltage requirements. Verify that the fast-on terminals are compatible with your connector specifications.
