Procurement Notes
Verify the complete part number including any suffixes against the manufacturer datasheet to ensure correct specifications. Confirm package dimensions and pin compatibility with your PCB layout before ordering. Check for RoHS compliance status if required by your assembly standards. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to use.
Selection Notes
Select this component when high current handling and low resistance are critical for power line filtering. Compare inductance values against target noise frequencies to ensure effective attenuation. Evaluate thermal management requirements based on the 9.5 A rating and ambient operating conditions. Consider mechanical stability needs for through-hole versus surface-mount alternatives.
Part Context
This component belongs to the WE-LPCC series from Würth Elektronik, specialized for common mode chokes in power applications. The series offers various inductance and current ratings to suit different filtering requirements. It is engineered for reliability in demanding electronic systems where consistent performance across wide temperature ranges is essential.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified cross-references or alternative part numbers within the same series. Ensure any substitute matches the 450 µH inductance, 9.5 A current rating, and 9.6 mΩ resistance specifications. Verify physical footprint compatibility for direct replacement without PCB redesign.
