FN2010A-20-08

Overview

The Schaffner FN2010A-20-08 is a single-phase, single-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 features screw terminal connections. Key electrical parameters include a capacitance of 100 nF, an inductance of 600 µH, and a leakage current of 0.74 mA. It functions reliably between -25°C and +100°C, with a power loss of 3.8 W at rated conditions.

Feature Summary

• Single-stage filtering configuration for effective noise suppression
• Chassis mount design with screw terminals for secure installation
• Operates across standard power frequencies up to 400 Hz

Applications

• Industrial machinery power conditioning
• Medical equipment electromagnetic compatibility
• General purpose power line filtering

Procurement Notes

Verify the specific datasheet version for the FN2010A-20-08 to confirm compliance certifications such as UL, CSA, or IEC/EN, as these vary by region and revision. Ensure the mounting hardware matches the specified M4 screw requirements. Cross-reference the terminal type to confirm screw posts rather than quick-connect variants found in other series models.

Selection Notes

Select this model when a single-stage solution is sufficient for the required attenuation levels. Compare against the FN2010-20-06 if quick-connect terminals are preferred over screw mounts. Consider the FN2060 series if higher current ratings or two-stage performance are necessary for stricter emission standards.

Part Context

This component belongs to the FN2010 series of single-phase EMI filters from Schaffner. It shares the same physical footprint and general electrical characteristics as the FN2010-20-06 but utilizes screw terminals instead of quick-connect tabs. The 'A' suffix typically denotes specific manufacturing revisions or regional compliance updates within the product family.

Replacement Considerations

FN2010-20-06 offers identical electrical performance with quick-connect terminals instead of screws. FN2010A-30-08 provides higher current capacity (30 A) with similar mounting and connection styles.
