B82791G2401N001

Overview

The B82791G2401N001 is a two-line common mode choke manufactured by EPCOS (TDK Electronics). It features a ferrite ring core and is designed for through-hole PCB mounting. The component has a nominal inductance of 15,000 µH (15 mH) per line with a maximum DC resistance of 1.35 Ω. It supports a current rating of 400 mA and operates within a temperature range of -40 °C to 125 °C. Electrical ratings include 80 V DC and 42 V AC.

Feature Summary

• Provides common mode noise suppression via dual winding configuration
• Utilizes ferrite ring core construction for electromagnetic interference filtering
• Designed for robust through-hole printed circuit board integration

Applications

• Power line filtering in electronic equipment
• Electromagnetic compatibility enhancement in industrial machinery
• Signal integrity protection in automotive electronics

Procurement Notes

Verify the specific manufacturer designation, as sourcing data references both EPCOS and TDK Electronics due to corporate restructuring. Confirm that the required package matches the through-hole specification and that the operating temperature range meets the application's thermal requirements. Ensure compliance with RoHS standards if mandated by the end product regulations.

Selection Notes

Select this component when high inductance values are required for low-frequency noise attenuation in power lines. The 400 mA current rating dictates suitability for lower-power signal or control circuits rather than high-current power delivery paths. Consider the physical dimensions and lead spacing for adequate PCB layout clearance during the design phase.

Part Context

This component belongs to the B82791 series of ring core chokes from EPCOS/TDK. These components are engineered for general-purpose electromagnetic interference suppression. The series offers various inductance and current combinations to suit different filtering needs across consumer, industrial, and automotive sectors.

Replacement Considerations

Cross-reference with other B82791 series variants having matching 15 mH inductance and 400 mA current ratings. Verify pinout compatibility and mechanical footprint before substituting to ensure seamless integration into existing designs.
