The component has a nominal inductance of 27 mH with a tolerance of 30%. It supports a maximum DC current of 2 A and exhibits a maximum DC resistance of 260 mohms. Rated for 250 V AC, it operates within a temperature range of -40 °C to +125 °C. The physical dimensions are approximately 33.6 mm in length and 32.6 mm in width.

Feature Summary

• Current-compensated design utilizing a ring core structure to minimize magnetic field interference
• Dual-channel configuration suitable for balanced DC line filtering applications
• Robust thermal performance allowing operation up to +125 °C

Applications

• Filtering on DC lines with balanced currents through both windings
• Power line chokes for general purpose noise suppression
• Common mode filter applications in industrial electronics

Procurement Notes

Verify the specific suffix N020 against official EPCOS/TDK documentation to confirm exact inductance and current ratings. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with the latest datasheet revisions to avoid discrepancies in electrical parameters or mechanical dimensions before finalizing orders.

Selection Notes

Select this component when balanced DC current flows through both windings, as unbalanced currents may bias the core and reduce filtering effectiveness. Consider the 2 A current rating and 260 mohm DC resistance for power loss calculations. Verify that the 27 mH inductance meets the required impedance characteristics for the target frequency range in the specific circuit design.

Part Context

This component belongs to the B82724 series of current-compensated ring core double chokes from EPCOS (TDK). The series offers various inductance values ranging from 1.8 mH to 100 mH with rated currents up to 6 A. These chokes are designed for power line applications requiring effective common mode noise suppression in compact radial leaded packages.

Replacement Considerations

Check for direct substitutes within the B82724 series with matching inductance and current ratings. Verify mechanical footprint compatibility for PCB mounting. Ensure alternative components maintain similar thermal stability and voltage ratings for equivalent performance in the application.
