B82724J2142N001

Overview

The B82724J2142N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and radial leaded construction with a rectangular form factor. The component has an inductance of 0.027 uH, a DC resistance of 0.46 Ω, and operates within a temperature range of -40 °C to +125 °C. It supports a rated voltage of 250 V AC and includes two functional elements with four terminals.

Feature Summary

• Current-compensated design utilizing a ferrite ring core for efficient magnetic field containment.
• Radial leaded through-hole mounting configuration suitable for standard PCB assembly.
• Dual-element structure providing common-mode noise suppression capabilities.

Applications

• Power line filtering in electronic equipment
• EMI suppression in general purpose circuits
• Input stage filtering for power supplies

Procurement Notes

Verify the specific suffix code against official TDK/EPCOS documentation to confirm exact electrical tolerances and compliance status. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the delivered components match the specified ferrite core material and dimensional requirements for your application.

Selection Notes

Select this component when a low-inductance current-compensated choke is required for differential mode noise reduction. Consider the 0.46 Ω DC resistance for power loss calculations. Verify that the 250 V AC rating meets the system voltage requirements and that the operating temperature range aligns with the environmental conditions.

Part Context

This part belongs to the B82724 series of power line chokes from EPCOS (now TDK Electronics). The series offers various inductance values and current ratings designed for electromagnetic compatibility applications. These components are widely used in industrial and consumer electronics to meet regulatory emission standards.

Replacement Considerations

Check for direct substitutes within the B82724 series with identical inductance and pinout. Verify mechanical dimensions and terminal spacing before substitution. Consult official cross-reference lists for equivalent parts from other manufacturers if necessary.
