Procurement Notes
Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified electrical parameters, including the 100 mH inductance and 150 mA current rating. Check for physical integrity and correct marking on the unshielded SMD package before integration into production workflows.
Selection Notes
Select this component when high inductance values are required for low-frequency noise attenuation in space-constrained designs. The 14x12.5 mm footprint accommodates the 100 mH value while maintaining a low profile of 7.8 mm. Ensure the circuit current does not exceed the 150 mA limit to prevent saturation or thermal issues.
Part Context
This component belongs to the WE-UCF series from Würth Elektronik, which specializes in surface-mount common mode chokes. The series is engineered for broad applicability across various electronic systems requiring effective EMI mitigation. The 744290104 variant specifically targets applications needing significant inductance in a standardized SMD form factor.
Replacement Considerations
Consult official Wurth Elektronik substitution guides for verified alternatives. Cross-reference key parameters such as inductance, current rating, and physical dimensions when evaluating potential substitutes.
