B82731M2401A033

Overview

The B82731M2401A033 is a current-compensated D-core double choke manufactured by TDK-EPCOS. It features a nominal inductance of 68 mH and a rated current of 400 mA. The component operates within a temperature range of -40 to +125°C and supports a rated voltage of 250 V AC. It utilizes a vertical through-hole mounting configuration with a maximum height of 20.50 mm.

Feature Summary

Current-compensated design for power line filtering
D-core ferrite construction for high inductance density
Vertical leaded package for PCB integration

Applications

Power line common mode noise suppression
Electromagnetic interference (EMI) filtering in electronic equipment
General purpose inductive components in industrial electronics

Procurement Notes

Verify the specific suffix 'A033' against official TDK-EPCOS documentation to confirm pinout, tolerance, and packaging details. Ensure the selected variant meets the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a high-inductance common mode choke is required for power line applications. Consider the 400 mA current rating and 250 V AC voltage limit during circuit design. Verify compatibility with vertical mounting constraints and operating temperature ranges.

Part Context

This part belongs to the B82731 series of current-compensated D-core double chokes. These components are designed for general-purpose inductive applications, offering robust performance in filtering and energy storage roles within various electronic systems.

Replacement Considerations

Cross-reference with other B82731 variants or equivalent D-core chokes from TDK-EPCOS. Verify inductance, current rating, and physical dimensions before substitution.
