Procurement Notes
Verify the specific package type and pin configuration against the official datasheet before integration. Confirm that the 2A current rating and 190 mH inductance meet the circuit requirements. Ensure the operating temperature range aligns with the final application environment. Cross-reference the manufacturer part number to avoid counterfeit components.
Selection Notes
Select this component when high inductance is required for low-frequency common mode noise suppression. The nanocrystalline core offers superior performance compared to standard ferrite cores in specific frequency bands. Consider the through-hole mounting style if higher mechanical robustness is needed compared to surface mount alternatives.
Part Context
This component belongs to the WE-CMBNC series, which specializes in common mode chokes using nanocrystalline technology. The series is designed for power line applications where high permeability and compact size are critical. Würth Elektronik focuses on providing reliable passive components for demanding electronic environments.
Replacement Considerations
Check for direct substitutes within the WE-CMBNC series with similar inductance and current ratings. Verify compatibility with existing PCB footprints if considering alternative mounting styles. Ensure any replacement maintains the same thermal and electrical specifications for safe operation.
