B82791H2351N001

Overview

The B82791H2351N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and is designed for power line applications with a rated voltage of 250 V AC. The component provides an inductance of 22 mH and supports a rated current up to 0.35 A. It operates within a temperature range of -40 °C to +125 °C. The device utilizes special core material to achieve high resonance frequency and saturation capability without potting.

Feature Summary

• Current-compensated ring core design for differential mode filtering
• High resonance frequency and saturation capability due to specialized core material
• Unpotted construction allowing for higher thermal performance

Applications

• Power line common mode chokes
• Differential mode noise suppression in electronic equipment

Procurement Notes

Verify the complete part number including suffixes such as N001 against official TDK/EPCOS documentation to ensure correct packaging and compliance status. Confirm that the specific variant matches the required inductance and current ratings for the target application, as minor suffix changes may affect mechanical or environmental specifications.

Selection Notes

Select this component for applications requiring robust differential mode filtering in compact spaces. The unpotted design offers advantages in thermal management compared to potted alternatives. Ensure the operating current remains below the rated limit to maintain inductance stability and prevent core saturation during peak load conditions.

Part Context

This component belongs to the B82791H series of power line chokes from EPCOS/TDK. These devices are engineered for general-purpose electromagnetic interference suppression in AC power circuits. The series typically includes various inductance values and current ratings to suit different power supply requirements.

Replacement Considerations

Check for direct substitutes within the B82791H series with matching inductance and current ratings. Verify mechanical dimensions and terminal configurations to ensure compatibility with existing PCB layouts before substituting.
