FN406B-6-02

Overview

The Schaffner EMC Inc. FN406B-6-02 is a single-phase power line filter module designed for PCB mounting. It features a rated voltage of 250 VAC and a current rating of 6 A. The component operates within a frequency range of 0 Hz to 400 Hz and utilizes solder pin termination for through-hole installation. Key electrical specifications include a leakage current of 2 µA. The device complies with UL, CSA, and IEC/EN standards.

Feature Summary

• Provides electromagnetic interference suppression for single-phase AC power lines
• Designed for direct printed circuit board mounting via solder pins
• Certified for medical equipment applications under relevant safety standards

Applications

• Medical electronic devices requiring low leakage current
• Industrial control systems operating at standard or variable frequencies up to 400 Hz
• General purpose electronics requiring single-stage EMI filtering

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct terminal configuration and certification status. Confirm that the required leakage current limits align with the specified 2 µA maximum for your application. Check for any recent product change notices regarding material composition or packaging updates before finalizing procurement orders.

Selection Notes

Select this component when a compact, PCB-mount solution is required for single-phase filtering. Ensure the system voltage does not exceed 250 VAC and the continuous current load remains within the 6 A limit. Consider the through-hole solder pin termination method during layout design. Verify that the 0 Hz to 400 Hz operational frequency range matches the power source characteristics.
