B82791H2202N010

Overview

The B82791H2202N010 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a rectangular construction with a ferrite core and radial leads. The component has a nominal inductance of 2200 µH, a maximum AC voltage rating of 250 V, and a current rating of 2 A. It operates within a temperature range of -40 °C to 125 °C. The package dimensions are approximately 15.3 mm in length, 7.4 mm in width, and 17.6 mm in height.

Feature Summary

• Compact design suitable for post-EMC tuning on finished PCBs
• High resonance frequency and saturation capability due to special core material and lack of potting
• Effective common mode filtering up to 300 MHz
• High stray inductance for symmetric interference suppression

Applications

• LED driver circuits
• Switch-mode power applications
• Design-post EMC micro-tuning on semi-finished PCBs

Procurement Notes

Verify the specific suffix N010 against official TDK-EPCOS documentation to confirm lead configuration and compliance status. Ensure the selected variant matches the required 2 A current rating and 250 V AC voltage specifications for the target power line application. Cross-reference the manufacturing date code to ensure availability of current production batches.

Selection Notes

Select this component when space constraints require a compact filter solution for high-frequency noise suppression. The current-compensated design minimizes DC resistance while maintaining effective common mode rejection. Consider the operating temperature range and physical dimensions to ensure compatibility with the final assembly enclosure and thermal management requirements.

Part Context

This part belongs to the B82791H series of small current-compensated ring core double chokes. These components are engineered for high-frequency EMC applications where size is critical. The series utilizes specialized ferrite materials to achieve performance characteristics that exceed standard wound inductors in terms of self-resonant frequency and saturation limits.

Replacement Considerations

Consult official TDK-EPCOS substitution guides for verified alternatives. Generic equivalents may not replicate the specific magnetic properties or dimensional tolerances required for high-frequency EMC filtering.
