Procurement Notes
Verify the specific package configuration and lead times directly with authorized distributors or the manufacturer. Confirm that the 21 A current rating aligns with your system's thermal management capabilities. Ensure compatibility with the 300V AC voltage rating for your intended circuit design before finalizing procurement orders.
Selection Notes
Select this component when high current handling and effective common mode noise attenuation are required. The nanocrystalline core offers advantages over traditional ferrite materials in terms of saturation characteristics. Consider the physical dimensions and mounting requirements to ensure adequate clearance on the PCB layout for thermal dissipation.
Part Context
This part belongs to the WE-CMBNC series, which focuses on nanocrystalline common mode chokes. These components are engineered for robust performance in challenging electromagnetic environments. The series provides solutions for filtering conducted emissions in power lines where standard ferrite cores may saturate under high load conditions.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified cross-reference part numbers. Ensure any substitute maintains equivalent inductance, current rating, and temperature specifications.
