B82734W2142B030

Overview

The B82734W2142B030 is a power line choke manufactured by EPCOS (TDK Electronics). It features a closed rectangular ferrite core and a current-compensated double choke design. The component has a rated inductance of 10 mH to 100 mH, a rated voltage of 300 V AC, and a maximum operating temperature of 125 °C. It utilizes a closed plastic coil former compliant with UL 94 V-0 standards.

Feature Summary

• Current-compensated double choke configuration for effective noise suppression
• Closed rectangular ferrite core construction
• Closed plastic coil former meeting UL 94 V-0 flammability rating

Applications

• Power line filtering
• Electromagnetic interference suppression in electronic circuits
• General purpose inductor applications requiring high current compensation

Procurement Notes

Verify the specific inductance value within the 10 mH to 100 mH range required for your circuit design, as this series covers a broad spectrum. Confirm that the 300 V AC rated voltage aligns with your system's electrical requirements. Ensure compatibility with the current-compensated topology before finalizing procurement specifications.

Selection Notes

Select this component when a current-compensated double choke is necessary to minimize common-mode noise while maintaining signal integrity. The closed ferrite core design offers superior shielding compared to open cores. Consider the 125 °C maximum operating temperature limit when evaluating thermal management strategies for dense circuit boards.
