B82724J8252N040

Overview

The B82724J8252N040 is a current-compensated ring core double choke from the EPCOS/TDK B82724J8 series, designed for power line and DC-link applications. It features a ferrite core with special winding technology for high resonance frequency. Key electrical parameters include an inductance of 22 mH, a maximum DC current rating of 6.7 A, and a maximum DC resistance of 135 mOhms. The component measures 31.3 mm in length, 18.5 mm in width, and 18.5 mm in height. It operates within a temperature range of -40°C to +125°C and is fully encapsulated for thermal stability.

Feature Summary

• Current-compensated ring core design for effective common mode interference suppression
• Fully encapsulated construction to enhance thermal stability and reduce local pollution
• Special winding technology ensures high resonance frequency performance

Applications

• Common mode interference suppression in power lines
• Switching mode power supply (SMPS) input filtering
• DC-link applications in frequency converters

Procurement Notes

Verify the specific suffix N040 against official TDK/EPCOS documentation to confirm lead time and availability status. Ensure the procurement channel provides valid traceability for automotive or industrial grade components. Cross-reference the full part number with the manufacturer's latest datasheet to confirm RoHS compliance and safety certifications relevant to your region.

Selection Notes

Select this component when high current handling up to 6.7 A is required alongside significant inductance for power line filtering. The horizontal mounting style and specific footprint dimensions must align with the PCB layout constraints. Consider the encapsulation benefits for environments requiring improved thermal management and protection against environmental contaminants compared to non-encapsulated alternatives.

Part Context

This component belongs to the B82724J8 series of power line chokes manufactured by EPCOS, now part of TDK Electronics. The series is characterized by current-compensated ring core double chokes suitable for AC power lines up to 250 V. These components are engineered for robust performance in industrial and consumer electronics, offering reliable common mode noise reduction in compact through-hole packages.

Replacement Considerations

Direct substitutes may include other B82724J8 variants with different inductance values but identical mechanical footprints, such as B82724J8222N040 or B82724J8332N040, provided electrical ratings meet the circuit requirements. Verify that any replacement maintains the same current compensation characteristics and encapsulation type to ensure consistent thermal and electromagnetic performance.
