Overview
The Schaffner FN406-0.5-02 is a single-phase power line filter designed for PCB mounting with through-hole solder pin termination. It features a rated voltage of 250 VAC and a rated current of 500 mA. The component operates within a frequency range of 0 Hz to 400 Hz and specifies a leakage current of 190 uA. Certified under UL, CSA, and IEC/EN standards, this ultra-compact EMI filter provides essential noise suppression for sensitive electronic circuits requiring reliable power line conditioning.
Feature Summary
- Ultra-compact physical design optimized for space-constrained printed circuit board layouts
- Single-stage EMC/EMI filtering capability for effective noise attenuation
- Through-hole solder pin termination ensuring secure mechanical and electrical connection
Applications
- Power supply input stages in consumer electronics
- Medical equipment internal power distribution
- Industrial control system signal conditioning
Procurement Notes
Verify the specific part number suffix against official TE Connectivity / Schaffner documentation to ensure correct configuration. Confirm that the 500 mA current rating and 250 VAC voltage limits align with the target application requirements. Check for RoHS compliance status and relevant safety certifications such as UL or CSA before finalizing procurement orders.
Selection Notes
Select this component when a low-current, single-phase solution is required for PCB-integrated noise suppression. Ensure the operating environment stays within the specified 0 Hz to 400 Hz frequency range. Consider the 190 uA leakage current limit if strict isolation standards apply to the end product design.
Part Context
This model belongs to the FN406 series of power line filters manufactured by TE Connectivity / Schaffner. The series offers various current ratings including 1 A and 6 A variants, all sharing similar compact form factors and mounting styles. These filters are engineered for general-purpose EMI suppression in single-phase AC applications.
Replacement Considerations
The FN406B-0.5-02 serves as a related variant within the same product family. Verify functional equivalence and pin compatibility before substitution. Consult official datasheets to confirm that alternative components meet identical voltage, current, and certification requirements.
