FN402-1-02

Overview

The Schaffner FN402-1-02 is a single-phase power line filter designed for printed circuit board (PCB) mounting. It features a rated voltage of 250 VAC and a continuous current rating of 1 A. The component operates within a frequency range of 0 Hz to 400 Hz and utilizes through-hole solder pin termination. Key electrical specifications include a leakage current of 373 uA and compliance with UL, CSA, and IEC/EN safety standards.

Feature Summary

• Designed as a low-cost PCB filter for electromagnetic interference suppression
• Supports through-hole installation via solder pin termination
• Certified for international safety standards including UL, CSA, and IEC/EN

Applications

• Single-phase AC power input filtering for electronic equipment
• Electromagnetic compatibility (EMC) mitigation in commercial power systems
• Power conditioning circuits operating at 50/60 Hz or up to 400 Hz

Procurement Notes

Verify the manufacturer part number FN402-1-02 against official TE Connectivity/Schaffner documentation to confirm specifications. Ensure the required safety certifications (UL, CSA, IEC/EN) meet the target application's regulatory requirements. Confirm that the 1 A current rating and 250 VAC voltage limit are sufficient for the specific circuit design before procurement.

Selection Notes

Select this component when a cost-effective, single-stage EMI filter is required for single-phase applications. It is suitable for designs prioritizing low profile and simple PCB integration over high-current handling. Consider the 373 uA leakage current if sensitive medical or precision analog circuits are involved. Verify that the through-hole package aligns with the manufacturing process.

Part Context

This component belongs to the FN402 series of power line filters manufactured by TE Connectivity under the Schaffner brand. The series offers various current ratings for single-phase applications. The FN402-1-02 specifically addresses the 1 A requirement within this lineup, providing a standardized solution for basic noise suppression needs in general-purpose electronics.

Replacement Considerations

The part number alias 800532-SF may be used interchangeably. For higher current requirements within the same form factor, consider other variants in the FN402 series such as FN402-1.6-02 or FN402-2.5-02.
