B82731M2182A030

Overview

The B82731M2182A030 is a current-compensated D core double choke manufactured by EPCOS (TDK Electronics). It features a rated AC voltage of 250V and a maximum DC resistance of 140mOhm. The component supports a rated current of 1.8A and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 21.00mm in length, 15.00mm in width, with a maximum height of 20.50mm. The device holds ENEC, UR, and VDE approvals.

Feature Summary

Current-compensated D core construction for double choke applications
High thermal stability operating up to +125°C
Certified for safety compliance including ENEC, UR, and VDE

Applications

Power line filtering
Common mode noise suppression
Industrial electronic equipment

Procurement Notes

Verify the specific suffix 'A030' against official TDK/EPCOS documentation to confirm exact pinout and packaging configuration. Ensure that the required inductance value aligns with the nominal range specified for the B82731M series. Confirm that the 1.8A current rating meets the operational requirements of the target circuit under maximum ambient temperature conditions.

Selection Notes

Select this component when a compact, current-compensated choke is required for 250V AC lines. The D core design offers high saturation characteristics suitable for power line applications. Consider the 140mOhm DC resistance for efficiency calculations. Verify space constraints against the 21x15x20.5mm footprint before integration into the PCB layout.

Part Context

This part belongs to the B82731M/H series of current-compensated double chokes. These components are designed for common mode interference suppression in power supply inputs. The series covers various inductance values and current ratings, providing a standardized solution for EMC filtering in industrial and consumer electronics.

Replacement Considerations

Check for direct cross-references within the B82731M series for different inductance or current ratings. Verify mechanical compatibility if substituting with similar D-core chokes from other manufacturers. Ensure replacement parts maintain equivalent safety certifications such as UL and VDE.
