FN405-1-02

Overview

The FN405-1-02 is a single-phase EMI/EMC power line filter module manufactured by TE Connectivity Schaffner. Designed for through-hole PCB mounting, it supports a rated voltage of 250 VAC and a continuous current of 1 A. The component operates within a frequency range of DC to 400 Hz and features solder pin termination. It exhibits a leakage current of 373 uA and complies with UL, CSA, and IEC/EN safety standards.

Feature Summary

• Single-stage electromagnetic interference suppression for AC power lines
• Through-hole construction with solder pin termination for printed circuit board integration
• Certified compliance with major international safety standards including UL, CSA, and IEC/EN

Applications

• Electromagnetic compatibility filtering in low-current electronic equipment
• Power supply input stages for devices operating at 400 Hz
• General-purpose noise suppression in single-phase AC circuits

Procurement Notes

Verify the manufacturer part number FN405-1-02 against official TE Connectivity Schaffner documentation to confirm specifications. Ensure the procurement source provides valid certification records for UL, CSA, and IEC/EN compliance. Cross-reference the 1 A current rating and 250 VAC voltage limits with the target application requirements before finalizing orders.

Selection Notes

Select this component when a single-stage, low-current EMI filter is required for PCB-mounted applications. The 1 A rating and 250 VAC specification define its operational limits. Consider the through-hole solder pin termination style for mechanical stability. Verify that the 373 uA leakage current meets the safety constraints of the end product design.

Part Context

This component belongs to the FN405 series of single-phase power line filters from Schaffner. The series offers various current ratings, with the FN405-1-02 specifically designated for 1 A applications. It utilizes a standardized form factor suitable for direct insertion into printed circuit boards, distinguishing it from chassis-mount or terminal block variants found in other Schaffner product lines.
