B82793C0113N201

Overview

The B82793C0113N201 is a surface-mount common-mode choke from the EPCOS B82793 series, designed for data and signal line applications. It features a ring core construction with bifilar winding and an LCP case rated UL 94 V-0. Key electrical parameters include an inductance of 11 µH, a rated current of 800 mA, and a DC resistance of 140 mOhm. The component supports a rated voltage of 42 V AC or 80 V DC and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 7.10 mm x 6.00 mm x 4.80 mm.

Feature Summary

• Suppresses asymmetrical interference coupled into lines while allowing data signals up to several MHz to pass unaffectedly.
• Qualified to AEC-Q200 standards for automotive reliability when inductance is less than or equal to 4.7 mH.
• Suitable for reflow soldering processes due to silicone potting and robust LCP casing.

Applications

• Suppression of asymmetrical interference on data and signal lines
• Automotive electronics requiring AEC-Q200 qualified components
• Signal integrity protection in high-frequency data transmission circuits

Procurement Notes

Verify that the specific part number matches the required inductance value of 11 µH, as the B82793 series contains variants with different inductance ratings. Confirm AEC-Q200 qualification status if the application requires it, noting that this qualification applies specifically to parts with inductance values of 4.7 mH or lower. Ensure the supplier provides documentation confirming the bifilar winding construction and UL 94 V-0 rated LCP material for compliance purposes.

Selection Notes

Select this component for applications requiring suppression of asymmetrical noise on signal lines without attenuating the desired data frequencies. The 800 mA current rating and low DC resistance make it suitable for power-sensitive signal paths. Consider the 7.10 mm x 6.00 mm footprint for PCB layout constraints. Verify thermal performance within the -40°C to +125°C operating range for the specific environment.

Part Context

This component belongs to the B82793C0/S0 family of common-mode chokes manufactured by EPCOS (now TDK Electronics). The 'C' suffix indicates a bifilar winding construction, which is optimized for suppressing asymmetrical interference. This family utilizes ferrite cores and LCP cases, offering a compact solution for EMC filtering in space-constrained electronic designs.

Replacement Considerations

Check datasheets for other B82793C0 variants with identical 11 µH inductance and 800 mA current ratings. Ensure any substitute maintains the same 140 mOhm DCR and 7.10 mm x 6.00 mm footprint to guarantee mechanical compatibility.
