B82793C0253N201

Overview

The B82793C0253N201 is a current-compensated double choke from the EPCOS B82793C series, designed for data and signal line applications. It features a bifilar winding construction on a ferrite core housed in an LCP case with UL 94 V-0 rating and silicone potting. The component provides a rated inductance of 2x5 µH and supports a rated current of 800 mA. It operates within a temperature range of -40°C to +125°C and is qualified to AEC-Q200 standards.

Feature Summary

• Suppression of asymmetrical interference coupled into lines while allowing data signals up to several MHz to pass unaffectedly
• Suitable for reflow soldering processes and RoHS-compatible manufacturing
• High rated currents combined with reduced component height for space-efficient designs

Applications

• Data line filtering in automotive electronics
• Signal line protection in industrial equipment
• EMC suppression in communication interfaces

Procurement Notes

Verify the specific ordering suffix N201 against the manufacturer's latest datasheet to confirm packaging details and reel specifications. Ensure the component meets the required AEC-Q200 qualification if used in automotive contexts. Cross-reference the bifilar winding type with system requirements for asymmetrical interference suppression. Confirm thermal performance limits align with the operational environment constraints.

Selection Notes

Select this model when asymmetrical noise suppression is required without attenuating high-frequency data signals. The bifilar winding distinguishes it from sector-wound variants suitable for symmetrical interference. Consider the 800 mA rated current and 2x5 µH inductance for matching circuit impedance. The AEC-Q200 qualification makes it appropriate for automotive applications requiring robust reliability under varying thermal conditions.

Part Context

This component belongs to the B82793C/S0 family of common-mode chokes manufactured by EPCOS (now TDK Electronics). The series offers rated inductances from 0.005 mH to 47 mH and rated currents from 100 mA to 1200 mA. The C-series specifically utilizes bifilar windings, contrasting with the S-series which uses sector windings for different interference profiles.

Replacement Considerations

B82793S513N201: Sector wound variant for symmetrical interference; different inductance (51 µH) and current (800 mA). B82793C502N201: Same bifilar construction but lower inductance (2x5 µH) and higher current (1200 mA). Verify winding type and electrical parameters before substitution.
