Procurement Notes

Verify the specific suffix N201 against official TDK/EPCOS documentation to confirm exact packaging and reel specifications. Ensure the procurement source provides traceability to the original manufacturer. Confirm that the delivered components match the B82793C series electrical characteristics and physical dimensions specified in the datasheet before integration into production.

Selection Notes

Select this component when designing circuits requiring suppression of common-mode noise on differential data lines in automotive or industrial settings. The 47 µH inductance and 150 mA current rating suit low-power signal transmission lines. Verify that the PCB footprint accommodates the 7.1x6mm package and that the operating environment remains within the -40°C to +125°C thermal range for optimal performance.

Part Context

This component belongs to the B82793 family of common-mode chokes manufactured by EPCOS, now part of TDK Electronics. The series is engineered for data and signal line protection, offering compact surface-mount solutions. These chokes are widely utilized in applications demanding robust electromagnetic interference suppression while maintaining signal integrity across various frequency bands.

Replacement Considerations

Consult official TDK/EPCOS substitution guides for verified alternatives within the B82793 series. Cross-reference inductance values, current ratings, and package dimensions to ensure functional equivalence. Do not assume compatibility with other manufacturers' parts without verifying pinout and electrical parameter alignment.
