B82793C0474N215

Overview

The EPCOS B82793C0474N215 is a surface-mount common-mode choke designed for data and signal line filtering. It features a current-compensated double choke construction with a bifilar winding on a ferrite core, housed in an LCP case with UL 94 V-0 rating and silicone potting. The component has a rated inductance of 470 µH (474 code) with a tolerance of ±30%. It supports a maximum rated current of 700 mA and operates within a temperature range of -40°C to +125°C. Electrical ratings include 42 V AC and 80 V DC. The physical dimensions are 7.1 mm x 6.0 mm with a maximum height of 4.8 mm.

Feature Summary

• Suppresses asymmetrical interference coupled into lines while allowing data signals up to several MHz to pass unaffectedly.
• Qualified to AEC-Q200 automotive standards for reliability in demanding environments.
• Suitable for reflow soldering processes due to its robust LCP case and silicone potting construction.

Applications

• Automotive data and signal line filtering
• Suppression of asymmetrical interference in communication interfaces
• Protection of electronic circuits in vehicle networks

Procurement Notes

Verify the specific suffix N215 against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required inductance value and current rating for your circuit design. Cross-reference the AEC-Q200 qualification status if automotive compliance is mandatory for your application.

Selection Notes

Select this component when filtering asymmetrical noise on high-speed data lines without attenuating the signal integrity. The bifilar winding configuration is optimal for applications requiring common-mode suppression while maintaining differential signal transmission. Consider the 700 mA current rating and 470 µH inductance to ensure compatibility with the target bus speed and power constraints.

Part Context

This component belongs to the B82793 series of ring-core common-mode chokes manufactured by EPCOS (TDK). The series offers various inductance values and current ratings tailored for data and signal line protection. The 'C' designation indicates a bifilar winding structure, distinguishing it from the 'S' series which uses sector winding for symmetrical interference suppression.

Replacement Considerations

Check for direct substitutes within the B82793 series with compatible inductance and current ratings. Verify that any alternative maintains the same footprint (7.1x6mm) and height constraints. Ensure the replacement also meets AEC-Q200 requirements if used in automotive contexts.
