B82793C0225N265

Overview

The B82793C0225N265 is a surface-mount common-mode choke from the EPCOS B82793-C series, designed for data and signal line applications. It features a current-compensated ring core with a ferrite core and bifilar winding technology. The component has a rated inductance of 2.2 mH (2200 µH) and a maximum DC current rating of 500 mA. Its direct current resistance (DCR) is specified at 0.4 Ohms. The device operates within an ambient temperature range of -40°C to +125°C and carries UL 94 V-0 flame retardant certification for its case.

Feature Summary

• Suppresses asymmetrical interference on data lines while allowing high-frequency signals to pass unaffected
• Utilizes a current-compensated ring core structure with bifilar winding for effective common-mode noise reduction
• Constructed with a case material certified as flame-retardant according to UL 94 V-0 standards

Applications

• Suppression of asymmetrical interference coupled into data lines
• Signal integrity protection in communication interfaces where high-frequency data passes unaffected
• Electromagnetic compatibility filtering in compact electronic assemblies

Procurement Notes

Verify the specific suffix N265 against the manufacturer's latest datasheet to confirm packaging details and availability status. Ensure that the ordering information matches the exact inductance tolerance and current ratings required for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring suppression of common-mode noise on differential or single-ended data lines. The 500 mA current rating and 0.4 Ohm DCR make it suitable for low-power signal processing applications. Verify that the 2.2 mH inductance value aligns with the specific frequency range of the interference to be filtered.

Part Context

This component belongs to the EPCOS B82793-C family of chokes for data and signal lines. These components are engineered to provide electromagnetic interference suppression in space-constrained surface-mount designs. The series utilizes ferrite ring cores to achieve high impedance for common-mode currents while maintaining signal integrity for differential data transmission.

Replacement Considerations

Consult official substitution lists for equivalent inductance and current ratings. Cross-reference with other B82793 variants if form factor constraints differ. Verify pinout compatibility and thermal characteristics before implementing any alternative part numbers.
