Procurement Notes
Verify the specific suffix code against official EPCOS documentation to confirm exact electrical tolerances and thermal ratings. Ensure the selected variant matches the required inductance value and current handling capacity for the target circuit design. Confirm compliance with regional environmental directives prior to integration.
Selection Notes
Select this component based on its 30 µH inductance and 1.6 A current rating requirements. Evaluate the vertical pin spacing and overall footprint dimensions to ensure compatibility with the printed circuit board layout. Consider the operating temperature range when designing for high-thermal environments.
Part Context
This component belongs to the B82721K series of common mode chokes designed for power line filtering. These ring core chokes are engineered to suppress electromagnetic interference in AC mains applications. The series offers various inductance values and current ratings to suit different household and industrial appliance requirements.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 30 µH inductance, 1.6 A current rating, and vertical 4-pin package dimensions.
