FN405-3-02

Overview

The FN405-3-02 is a single-phase EMC/EMI power line filter module 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 3 A. It operates within a frequency range of DC to 400 Hz. The unit includes an inductance value of 24 mH and complies with UL, CSA, and IEC/EN standards.

Feature Summary

• Designed for easy and fast printed circuit board mounting
• Provides single-stage electromagnetic interference suppression
• Supports low leakage current operation

Applications

• General purpose electronic equipment
• Power supply input stages
• Industrial control systems

Procurement Notes

Verify the manufacturer designation as TE Connectivity / Schaffner when sourcing. Confirm compliance certifications such as UL and CSA are required for your specific regional regulations. Ensure the through-hole package and solder pin termination match your PCB layout requirements before finalizing procurement.

Selection Notes

Select this model when a 3 A current rating and 250 VAC voltage rating are required for single-phase applications. The 24 mH inductance provides standard attenuation for common noise frequencies. Consider the physical dimensions and thermal limits if multiple units are mounted closely on a single board.

Part Context

This component belongs to the FN405 series of PCB-mounted power line filters. The series offers various current ratings to suit different power levels while maintaining a consistent form factor for standardized design integration across multiple product lines from Schaffner.

Replacement Considerations

Publicly confirmed substitute part numbers include 5500.2005 from SCHURTER Inc. and B84110A0000A005 from TDK. Verify electrical parameters and physical footprint compatibility before substitution.
