• Single-phase electromagnetic interference filtering capability

Applications

• Medical electronic devices
• PCB-mounted power supply units
• Chassis mounted equipment interfaces

Procurement Notes

Verify the specific part number against official Schaffner documentation to confirm the exact current rating suffix. Ensure compatibility with required medical safety certifications and PCB footprint dimensions before procurement. Cross-reference manufacturer datasheets for precise leakage current specifications relevant to your application.

Selection Notes

Select this component when a low-cost, single-phase EMI filter is required for medical-grade PCB assemblies. Consider the 1 A current rating and 250 VAC voltage limit during design. Evaluate space constraints as it is a compact PCB mount solution compared to larger chassis filters.

Part Context

This component is part of the Schaffner FN402 series, which offers various current ratings for single-phase applications. The 'B' designation typically indicates medical suitability within this family. It serves as a compact alternative to bulkier chassis-mounted filters for embedded power systems.

Replacement Considerations

Compatible substitutes include other FN402B variants with different current ratings such as FN402B-0.5-02 or FN402B-2.5-02, provided electrical ratings match the design requirements.
