B82724J8322N040

Overview

The B82724J8322N040 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It is designed for DC-link and power line applications. The component features a vertical termination style with dimensions of 31.3 mm x 18.5 mm x 33.2 mm. It operates at a rated voltage of 250 V AC (50/60 Hz) or 800 V DC, with a test voltage of 2000 V AC for 2 seconds. The rated temperature is +70 °C.

Feature Summary

• Current-compensated ring core design for effective noise suppression
• Suitable for both DC-link and general power line filtering
• Vertical radial termination for through-hole mounting

Applications

• DC-link circuits in power electronics
• Power line interference suppression
• Common mode noise filtering in industrial equipment

Procurement Notes

Verify the specific suffix N040 against official TDK/EPCOS documentation to confirm packaging and tape-and-reel specifications. Ensure the operating environment remains within the +70 °C rated temperature limit. Confirm that the 250 V AC / 800 V DC ratings align with your circuit requirements before procurement.

Selection Notes

Select this component when a current-compensated double choke is required for common mode noise reduction in power lines. It is appropriate for applications needing high resonance characteristics and robust construction. Verify that the vertical package fits the PCB layout constraints and that the 31.3 mm length is acceptable.

Part Context

This part belongs to the B82724J8 series of power line chokes from EPCOS/TDK. These components are engineered for high reliability in demanding electronic environments. The series utilizes ferrite cores with epoxy coating and polycarbonate cases, ensuring compliance with safety standards such as UL 94 V-0 for flame resistance.

Replacement Considerations

Check for direct substitutes within the B82724J8 series with different inductance values if electrical parameters differ. Ensure any replacement maintains the same vertical pin configuration and physical footprint to fit existing board layouts without modification.
