B82724J8302N040

Overview

The B82724J8302N040 is a current-compensated ring core double choke from the EPCOS (TDK) B82724A/J series. It features an inductance of 15 mH and a rated current of 3 A. The component has a DC resistance of 1.1 Ohm and operates within a temperature range of -40°C to +125°C. Designed for horizontal mounting, it utilizes a ferrite core construction suitable for power line applications up to 250 V AC.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• Ferrite core construction ensuring low DC resistance and high efficiency
• Robust performance in high-temperature environments up to +150°C

Applications

• Power line filtering in industrial electronics
• EMI suppression in automotive electronic systems
• Noise reduction in consumer information and communication technology devices

Procurement Notes

Verify the specific suffix code against official TDK/EPCOS documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing board layouts regarding horizontal mounting dimensions and lead spacing. Cross-reference datasheet revisions to confirm material compliance and operating temperature ratings prior to integration.

Selection Notes

Select this component for applications requiring high-current handling with significant common mode noise attenuation. The 3 A rating and 15 mH inductance make it suitable for robust power line filtering. Consider the horizontal package profile for space-constrained PCB designs where vertical height is limited but footprint area is available.

Part Context

This part belongs to the B82724A/J series of power line chokes manufactured by EPCOS, now part of the TDK Group. The series is engineered for demanding environments, offering stability across wide temperature ranges. These components are integral to electromagnetic interference mitigation in modern electronic systems requiring reliable signal integrity.

Replacement Considerations

Consult official TDK substitution guides for direct equivalents. Verify that any alternative maintains the 15 mH inductance, 3 A current rating, and horizontal form factor to ensure mechanical and electrical compatibility without redesigning the host circuit board.
