B82791G2251N020

Overview

The B82791G2251N020 is a current-compensated ring core common mode choke manufactured by EPCOS (TDK Electronics). It features a ferrite core and through-hole mounting with four terminals. The component has a nominal inductance of 47 mH at 10 kHz, a maximum height of 8.00 mm, and a maximum length of 17.50 mm.

Feature Summary

• Utilizes a current-compensated ring core design for effective noise suppression
• Constructed with a ferrite core material for high-frequency performance
• Encased in a compact rectangular housing suitable for space-constrained layouts

Applications

• Power line filtering in electronic equipment
• Electromagnetic compatibility (EMC) suppression circuits
• Signal integrity protection in communication interfaces

Procurement Notes

Verify the specific suffix N020 against official TDK/EPCOS documentation to confirm terminal configuration and insulation ratings. Ensure the selected variant matches the required inductance tolerance and rated current specifications for the target power line application. Cross-reference the manufacturer's latest datasheet to validate compliance with regional safety standards.

Selection Notes

Select this component when a high inductance value of 47 mH is required for low-frequency common mode noise attenuation. The through-hole package facilitates robust mechanical attachment in industrial or high-reliability environments. Evaluate the physical dimensions against the PCB footprint constraints before finalizing the design integration.

Part Context

This part belongs to the B82791 series of power line common mode chokes designed for general-purpose applications. The series offers various inductance values and current ratings to suit different power supply requirements. As an EPCOS product, it integrates into broader electromagnetic interference mitigation strategies within consumer and industrial electronics.

Replacement Considerations

Consult the official TDK replacement guide for direct equivalents. Verify that any substitute maintains the 47 mH inductance and compatible physical envelope to ensure board compatibility without redesign.
