B82731M2701A030

Overview

The B82731M2701A030 is a power line choke manufactured by EPCOS (TDK). It features an inductance of 27 mH at 10 kHz and supports a rated current of 700 mA. The component has a typical DC resistance of 1 Ohm and operates within a temperature range of -40 to 125°C. It utilizes through-hole mounting with a maximum height of 20.50 mm.

Feature Summary

• Provides common-mode noise suppression for power lines
• Supports two power lines via current-compensated design
• Utilizes through-hole mounting for secure installation

Applications

• Power line filtering
• Common-mode noise suppression
• Electronic equipment input stages

Procurement Notes

Verify the manufacturer designation as EPCOS or TDK, as both names are associated with this component lineage. Confirm the specific suffix A030 matches the required packaging and pin configuration. Ensure the inductance value of 27 mH and current rating of 700 mA align with circuit requirements before procurement.

Selection Notes

Select this component when common-mode noise suppression is required for dual power lines. The 27 mH inductance and 700 mA current rating suit applications needing moderate filtering without excessive voltage drop. Verify that the through-hole package fits the PCB layout and that the operating temperature range meets environmental conditions.

Part Context

This part belongs to the B82731 series of power line chokes from EPCOS/TDK. These components are designed for electromagnetic interference suppression in AC/DC power supplies and other electronic devices. The series offers various inductance values and current ratings to accommodate different filtering needs.

Replacement Considerations

Check for direct substitutes within the B82731 series with compatible inductance and current ratings. Verify pin compatibility and physical dimensions for board-level replacement. Consult official TDK/EPCOS documentation for approved alternative part numbers.
