B82793S0253N201

Overview

The B82793S0253N201 is a surface-mount common-mode choke from the EPCOS (TDK) B82793 series, designed for data and signal line filtering. It features a ring core construction with an LCP case and sector winding. Key electrical parameters include an inductance of 25 µH at 100 kHz, a rated current of 800 mA, and a maximum DC resistance of 110 mΩ. The component operates within a temperature range of -40°C to +125°C and carries AEC-Q200 certification. Physical dimensions are 7.10 mm x 6.00 mm with a maximum height of 4.80 mm.

Feature Summary

• High-rated current capability with reduced component height
• AEC-Q200 qualified for automotive reliability standards
• Sector winding construction on ferrite ring core
• UL 94 V-0 rated LCP case with silicone potting

Applications

• Automotive data bus signal line filtering
• Common-mode noise suppression in electronic circuits
• Protection of high-speed data interfaces

Procurement Notes

Verify the specific suffix N201 corresponds to the required tolerance and packaging configuration. Confirm AEC-Q200 compliance if automotive qualification is mandatory. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability. Check for RoHS compliance status as per current regulatory requirements.

Selection Notes

Select this component when a compact surface-mount solution is required for signal lines carrying up to 800 mA. The 25 µH inductance value is suitable for specific frequency attenuation needs. Consider the 110 mΩ DCR limit for power loss calculations. The wide operating temperature range supports harsh environment deployment.

Part Context

This part belongs to the B82793C/S0 family of common-mode chokes manufactured by EPCOS, now part of TDK Electronics. The series offers various inductance values and current ratings. The 'S' designation indicates sector winding, distinguishing it from bifilar wound variants. These components are engineered for robust performance in demanding applications.

Replacement Considerations

Direct substitutes within the same series include B82793C0253N201, which shares similar electrical characteristics but utilizes bifilar winding instead of sector winding. Verify pinout compatibility and physical footprint alignment before substitution.
