FN2090-20-06

Overview

The Schaffner FN2090-20-06 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 20 A. The component operates within a frequency range of 0 Hz to 400 Hz and utilizes fast-on terminals for connection. Key electrical parameters include a leakage current of 930 µA, an inductance of 8 mH, and a capacitance of 470 nF. It features a built-in discharge resistor of 330 kΩ and maintains a maximum power loss of 7.7 W at full load.

Feature Summary

• Two-stage filtering architecture provides enhanced attenuation for electromagnetic interference across the operational frequency spectrum.
• Integrated safety discharge resistor ensures rapid voltage reduction upon disconnection from the power source.
• Chassis mount design with fast-on terminals facilitates secure installation and straightforward wiring integration.

Applications

• Industrial machinery power supply input stages
• Medical equipment internal power conditioning
• Information technology hardware power interfaces

Procurement Notes

Verify the specific suffix code against official datasheets to confirm terminal type and mounting configuration. Ensure the selected variant matches the required current rating and voltage specifications for the target application. Cross-reference manufacturer part numbers with distributor listings to confirm authenticity and availability status before finalizing procurement orders.

Selection Notes

Select this model when a single-phase solution requires 20 A capacity with robust EMI suppression. The two-stage design suits applications needing higher attenuation than single-stage filters. Verify that the chassis mounting style and fast-on terminal dimensions align with the system enclosure layout and connector requirements.

Part Context

This component belongs to the FN2090 series, which comprises single-phase AC/DC power line filters. The series offers various current ratings and mounting options, including chassis and flange configurations. These filters are engineered for general industrial and commercial use, providing reliable noise suppression in power distribution systems.

Replacement Considerations

Direct substitutes may include other Schaffner FN2090 variants with adjusted current ratings or terminal types. Verify compatibility by comparing electrical parameters, physical dimensions, and certification requirements. Consult official cross-reference lists for approved alternative part numbers.
