Procurement Notes
Verify the specific suffix N001 against official TDK documentation to confirm exact electrical tolerances and packaging details. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Cross-reference the datasheet revision date to guarantee compatibility with current design requirements and regulatory standards.
Selection Notes
Select this component when a 10 A current rating and 1.8 mH inductance are required for 250 V AC systems. Consider the through-hole package constraints and physical dimensions during PCB layout. Evaluate the 14 mOhm DC resistance impact on system efficiency and thermal management within the specified -40°C to 125°C operating environment.
Part Context
This part belongs to the B82725A series of power line chokes from EPCOS (TDK). The series offers various inductance values and current ratings for different power line filtering needs. These components are widely used in electromagnetic compatibility (EMC) designs to mitigate conducted interference on AC mains connections.
Replacement Considerations
Check for direct substitutes within the B82725A series or equivalent models from other manufacturers that match the 1.8 mH inductance, 10 A current rating, and 250 V AC voltage specifications. Verify pinout compatibility and mechanical footprint alignment before substitution.
