Procurement Notes
Verify the specific part number against official manufacturer documentation to ensure accuracy. Confirm that the required electrical parameters, such as inductance and current ratings, align with the design specifications. Check for any updated compliance certifications or packaging variations before finalizing procurement decisions.
Selection Notes
Select this component when a high-inductance common mode choke is required for low-current applications. The 1A rating and 500 µH value suit sensitive data lines needing significant noise attenuation. Ensure the PCB footprint accommodates the 9.2mm x 6mm package dimensions and verify thermal management capabilities for the operating environment.
Part Context
This component is part of the WE-SL2 series from Würth Elektronik, which specializes in surface mount filter solutions. The series offers various inductance values tailored for different noise suppression requirements. The 744223 specifically targets applications demanding higher inductance within a standard SMD form factor.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified substitute part numbers. Cross-reference alternative components based on identical inductance, current rating, and physical dimensions to ensure compatibility without redesigning the circuit layout.
