Procurement Notes
Verify the complete part number including the suffix N040 to ensure correct packaging and specifications. Confirm that the 12 A rated current and 3.3 mH inductance align with the specific circuit requirements. Check for UL file number E70122 certification if regulatory compliance is mandatory for the end application.
Selection Notes
Select this component when a 3.3 mH inductance at 12 A is required for power line chokes. Ensure the horizontal through-hole package fits the PCB layout constraints. Compare against other B82725A variants if different inductance or current ratings are needed for the specific power stage design.
Part Context
This component belongs to the B82725A family of power line chokes manufactured by EPCOS (TDK). These devices are engineered for robust performance in demanding industrial settings. The series offers various inductance and current combinations while maintaining consistent physical dimensions and mounting styles for standardized integration.
Replacement Considerations
Other B82725A series parts with identical mechanical dimensions may serve as alternatives if electrical parameters match. Verify pinout compatibility and thermal characteristics before substitution.
