B82724J2102N021

Overview

The B82724J2102N021 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features an inductance of 39 mH with a tolerance of 30%. The component supports a maximum DC current of 1 A and has a typical DC resistance of 750 mOhms. Designed for vertical radial mounting, it operates within a temperature range of -40°C to +125°C. The ferrite core unit measures 31.3 mm in length, 18.5 mm in width, and 33.2 mm in height.

Feature Summary

Current-compensated ring core design for power line filtering
Vertical radial leaded termination for through-hole mounting
Ferrite core construction providing high inductance stability

Applications

Power line chokes for AC mains filtering
EMI suppression in industrial electronic equipment
Common mode noise reduction in power supply inputs

Procurement Notes

Verify the manufacturer designation as EPCOS or TDK Electronics on the component body and datasheet. Confirm the specific suffix N021 matches the required 39 mH inductance and 1 A current rating. Ensure the vertical radial package dimensions align with the PCB layout constraints. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a high inductance value of 39 mH is required for common mode noise suppression at low currents up to 1 A. The vertical mounting style is suitable for applications requiring minimal PCB footprint area but allowing for greater component height. Verify that the operating environment remains within the specified -40°C to +125°C temperature range.

Part Context

This part belongs to the B82724J series of power line chokes from EPCOS/TDK. These components are designed for general EMI suppression in AC power lines. The series offers various inductance values and current ratings, with the J variant typically indicating specific core material and winding characteristics optimized for common mode interference.
