Procurement Notes
Verify the specific datasheet version when ordering, as manufacturing updates may occur. Confirm that the radial lead configuration matches your PCB layout requirements. Ensure the 6.5A current rating meets your circuit's peak load demands. Check for any specific packaging variations if purchasing in bulk quantities from authorized distributors.
Selection Notes
Select this component when high common mode rejection is required in space-constrained power lines. The 450 µH inductance provides effective noise suppression for moderate frequency ranges. Consider the 10 mΩ DCR for efficiency calculations in low-voltage applications. The wide operating temperature range makes it suitable for harsh environmental conditions.
Part Context
This part belongs to the WE-CMB HC series, which focuses on high-current common mode chokes. The series is engineered for durability in demanding applications. The 'HC' designation typically indicates high-current capabilities compared to standard variants. Würth Elektronik designs these components to meet stringent automotive and industrial standards.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. Evaluate other WE-CMB series components only if they match the 450 µH inductance and 6.5A current rating exactly. Verify pin compatibility and physical dimensions before considering alternative manufacturers.
