Procurement Notes
Verify the specific ordering suffix against the official EPCOS/TDK datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the component meets the required AEC-Q200 qualification status for your specific application environment. Cross-reference the pinout and mechanical dimensions with the latest package drawing before integration.
Selection Notes
Select this component for applications requiring robust common-mode filtering on data lines with high current demands up to 1200 mA. The bifilar winding and ferrite core provide effective noise suppression while maintaining signal integrity. Consider the -40°C to +125°C operating range for harsh automotive or industrial environments where thermal stability is critical.
Part Context
This part belongs to the B82790C/S series of common-mode chokes manufactured by EPCOS (TDK Electronics). The series offers ring-core inductors ranging from 0.005 mH to 47 mH with rated currents between 100 mA and 1200 mA. These components are specifically engineered for data and signal lines, providing compact solutions for electromagnetic compatibility in modern electronic systems.
Replacement Considerations
Consult the official EPCOS replacement guide for verified cross-references. Ensure any substitute maintains the same inductance value, current rating, and AEC-Q200 certification if automotive compliance is required.
