Procurement Notes
Verify the specific suffix codes against the manufacturer datasheet to ensure correct inductance and current ratings. Confirm RoHS compliance status and packaging details directly with authorized distributors. Cross-reference the part number with official Wurth Elektronik documentation to avoid counterfeit components or incorrect variants.
Selection Notes
Select this component when high saturation current and low DC resistance are required for power line chokes. The nanocrystalline core offers superior performance compared to standard ferrite cores at lower frequencies. Ensure the PCB layout accommodates the through-hole footprint and physical dimensions of 14x7.5x16 mm.
Part Context
This component belongs to the WE-CMBNC series from Würth Elektronik, which specializes in nanocrystalline common mode chokes. The series is engineered for applications requiring high efficiency and compact size. The 7448014501 variant specifically targets power line filtering needs with its 4.5 A current rating.
Replacement Considerations
Check Wurth Elektronik's RedExpert tool for verified substitutes. Compare inductance, current rating, and physical dimensions before substitution. Ensure any alternative maintains the same nanocrystalline core characteristics for equivalent EMI performance.
