B82720K2301N040

Overview

The B82720K2301N040 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core with epoxy coating and a polycarbonate case. The component has an inductance of 12 mH, a maximum DC current rating of 300 mA, and a typical DC resistance of 1.1 Ohms. It operates within a temperature range of -40 °C to +125 °C. The device utilizes a vertical through-hole mounting style with four terminals.

Feature Summary

Current-compensated design for power line applications
Ferrite core construction with UL 94 V-0 rated epoxy and polycarbonate housing
Vertical PCB mount configuration

Applications

Power line filtering
Common mode noise suppression
General purpose inductor circuits

Procurement Notes

Verify the specific suffix against official TDK/EPCOS documentation to confirm exact electrical tolerances and packaging details. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the part number with the manufacturer's latest datasheet to confirm availability and any potential obsolescence notices before finalizing orders.

Selection Notes

Select this component for applications requiring common mode chokes with a 12 mH inductance and 300 mA current handling capability. The wide operating temperature range supports use in industrial environments. Verify that the through-hole footprint dimensions align with the target PCB layout constraints.

Part Context

This component belongs to the B82720 series of current-compensated ring core double chokes. These devices are designed for AC power line filtering and are characterized by their compact rectangular construction. The series offers various inductance values tailored for different power supply noise suppression requirements.

Replacement Considerations

Check for direct substitutes within the B82720 series or equivalent models from other manufacturers offering identical 12 mH inductance and 300 mA ratings. Ensure mechanical compatibility and thermal performance match the original specifications.
