B82793C0104N201

Overview

The B82793C0104N201 is a current-compensated double choke from the EPCOS B82793C0/S0 series, designed for data and signal line applications. It features a ferrite core with an LCP case (UL 94 V-0) and silicone potting. The component has a rated inductance of 100 µH and a rated current of 500 mA. It supports a rated voltage of 42 V AC or 80 V DC. The device utilizes bifilar winding construction and is qualified to AEC-Q200 standards for inductances greater than 4.7 mH.

Feature Summary

• Suppresses asymmetrical interference coupled into lines while allowing data signals up to several MHz to pass unaffectedly.
• Suitable for reflow soldering processes and RoHS-compatible.
• High-rated current capability combined with reduced component height.

Applications

• Data and signal line filtering
• Automotive electronics systems
• Industrial equipment EMC suppression

Procurement Notes

Verify the specific suffix code against official TDK/EPCOS documentation to confirm exact electrical tolerances and packaging specifications. Ensure the procurement source provides valid traceability for automotive-grade components requiring AEC-Q200 qualification. Cross-reference the manufacturer part number with the latest datasheet revisions to avoid discrepancies in mechanical dimensions or material certifications.

Selection Notes

Select this component when suppressing asymmetrical interference on data lines without attenuating high-frequency signal integrity is required. The bifilar winding design ensures effective common-mode noise reduction. Consider the 500 mA rated current and 100 µH inductance values to ensure compatibility with the target circuit's power and signal requirements within the specified temperature range.

Part Context

This component belongs to the B82793C0/S0 family of common-mode chokes manufactured by EPCOS, now part of TDK Electronics. The series offers various inductance values ranging from 0.005 mH to 47 mH with rated currents between 100 mA and 1200 mA. These ring-core chokes are engineered for robust performance in demanding electronic environments, providing reliable electromagnetic compatibility solutions.

Replacement Considerations

Check for direct substitutes within the B82793C0/S0 series that match the 100 µH inductance and 500 mA current rating. Verify mechanical footprint compatibility with the existing PCB layout. Confirm that any alternative maintains the same AEC-Q200 qualification status if used in automotive applications.
