B82724J8532N040

Overview

The B82724J8532N040 is a current-compensated ring core double choke from the EPCOS/TDK B82724J series, designed for DC-link and power line applications. It features a ferrite core with specialized winding technology to achieve high resonance frequency. The component provides an inductance of 3.3 mH at 10 kHz, supports a maximum DC current of 4.3 A, and exhibits a typical DC resistance of 26 mOhms. Its physical dimensions are 31.3 mm x 18.5 mm x 33.2 mm. Fully encapsulated for thermal stability and pollution resistance, it operates within a temperature range suitable for industrial environments.

Feature Summary

• Current-compensated ring core design for effective common mode interference suppression
• Specialized winding technology ensures high resonance frequency performance
• Fully encapsulated construction enhances thermal stability and reduces local contamination

Applications

• DC-link filtering in power electronics
• Common mode noise suppression in switch-mode power supplies
• High-voltage application circuits
• Frequency converter systems

Procurement Notes

Verify the specific suffix N040 against official TDK/EPCOS documentation to confirm lead frame configuration and packaging details. Ensure the selected variant matches the required inductance tolerance and current rating for the target circuit. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when high current handling and compact form factor are required for power line chokes. The 3.3 mH value suits moderate filtering needs where 4.3 A continuous current is necessary. Consider the through-hole mounting style and specific dimensional constraints of the PCB layout during integration planning.

Part Context

This part belongs to the B82724J series of power line chokes manufactured by EPCOS, now part of TDK Electronics. The series is characterized by its use in demanding industrial and automotive environments, offering robust performance in DC-link and AC power line applications with high thermal resilience.

Replacement Considerations

Consult official TDK cross-reference lists for direct substitutes. Verify that alternative parts match the 3.3 mH inductance, 4.3 A current rating, and 26 mOhm DCR specifications while maintaining compatible physical dimensions and mounting requirements.
