Procurement Notes

Verify the exact part number suffix against the manufacturer's latest datasheet to confirm terminal configuration and fuse ratings. Ensure the mounting hole pattern matches your enclosure design. Confirm that the ambient temperature derating curves align with your operational environment requirements before finalizing procurement.

Selection Notes

Select this model based on the requirement for a 13 A current capacity and 250 VAC operation. Evaluate the available insertion loss specifications against your specific EMC emission limits. Consider the physical dimensions and mounting style to ensure compatibility with the target system's mechanical constraints.

Part Context

This component belongs to the FN420 series of single-phase EMI filters from Schaffner. The series is engineered for general industrial and commercial applications requiring robust noise suppression. The FN420-1-13 variant specifically denotes the 13 Ampere current rating within this product family, distinguishing it from other current-capacity options available in the same chassis form factor.

Replacement Considerations

Cross-reference with equivalent models from other manufacturers only if they match the 13 A rating, 250 VAC voltage, and identical mounting footprint. Verify that substitute components meet the same regulatory certifications and insertion loss performance levels as the original specification.
