FN405-10-02

Overview

The FN405-10-02 is a single-phase EMC/EMI power line filter manufactured by TE Connectivity Schaffner. It features a through-hole mounting style with solder pin termination for PCB integration. The component has a voltage rating of 250 VAC and a current rating of 10 A. It operates within a frequency range of 0 Hz to 400 Hz. Key electrical specifications include a leakage current of 373 uA. The unit weighs 40 g and holds UL, CSA, and IEC/EN compliance certifications.

Feature Summary

• Single-stage filtering configuration designed for electromagnetic interference suppression
• Through-hole construction with solder pin terminals for printed circuit board mounting
• Certified for international safety standards including UL, CSA, and IEC/EN

Applications

• General purpose electronic equipment requiring EMI/EMC protection
• Power supply input stages in industrial control systems
• Medical device power interfaces

Procurement Notes

Verify the specific current rating against application requirements, as datasheet discrepancies exist between 10 A and 500 mA listings. Confirm package dimensions and pin spacing match the target PCB layout. Ensure compliance with RoHS directives if required by the end product. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when a single-phase filter with a 10 A capacity is required for low-frequency applications up to 400 Hz. The through-hole design suits environments where mechanical robustness is prioritized over surface area constraints. Consider the 250 VAC rating for standard mains voltage applications. Evaluate the physical footprint against available board space, noting the 40 g weight may impact vibration-sensitive designs.

Part Context

This part belongs to the FN405 series of PCB-mount power line filters from Schaffner. The series offers various current ratings to accommodate different load requirements while maintaining consistent form factors and mounting styles. The FN405-10-02 represents the higher current variant within this specific low-profile family, designed for compact integration into power distribution modules.
