FN406B-8.4-02

Overview

The Schaffner FN406B-8.4-02 is a single-phase EMC/EMI power line filter designed for PCB mounting via through-hole PC pins. It supports a voltage rating of 250 VAC and operates within a frequency range of 0 Hz to 400 Hz. The component handles a rated current of 8.4 A and features an inductance of 300 µH. It complies with UL, CSA, and IEC/EN standards.

Feature Summary

• Single-stage EMI filtering architecture
• Through-hole PCB pin termination
• Compliance with international safety standards

Applications

• General power supplies
• Battery chargers
• Portable devices

Procurement Notes

Verify the specific datasheet version for the FN406B-8.4-02 to confirm exact leakage current values and thermal derating curves. Ensure the PCB layout accommodates the through-hole pin spacing and that the operating temperature range of -25°C to 100°C aligns with the final enclosure design requirements.

Selection Notes

Select this model when high current capacity up to 8.4 A is required in a compact form factor. The 300 µH inductance provides effective noise attenuation for general applications. Verify that the 250 VAC rating matches the system voltage and that the through-hole mounting style is compatible with the assembly process.

Part Context

This component belongs to the FN406 series of ultra-compact EMC filters manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series is characterized by its small footprint and high current handling capabilities, making it suitable for space-constrained electronic equipment requiring robust power line filtering.

Replacement Considerations

Check for FN406B-6-02 or FN406B-1-02 if lower current ratings are acceptable. Verify pin compatibility and inductance values before substituting.
