Procurement Notes

Verify the specific datasheet version for the FN2450G-20-61 to confirm exact leakage current values, as sources vary between 0.73 mA and 0.94 mA descriptions. Ensure the ordering suffix matches the required terminal configuration and certification marks for your target market. Cross-reference the manufacturer part number with TE Connectivity/Schaffner official documentation to avoid confusion with similar series variants like the FN2450B or FN2450F.

Selection Notes

Select this component when a single-phase filter is required for currents up to 20 A at 250 VAC. The chassis mount style suits applications where panel integration is necessary. Verify that the operating frequency range of 0–400 Hz aligns with the system's power requirements. Consider the physical dimensions and terminal type during mechanical design integration.

Part Context

This component belongs to the Schaffner FN2450 series of power line filters. The series is designed for general industrial and commercial applications requiring effective noise suppression. The FN2450G variant specifically denotes the 20 A rating and G-series construction characteristics within the broader product family.

Replacement Considerations

Direct substitutes within the same series include the FN2450G-10-61 (10 A) and FN2450G-6-61 (6 A) for lower current needs. For higher current requirements, check the FN2450G-30-61 if available. Ensure any replacement maintains the same voltage rating and mounting style.
