Overview

The Würth Elektronik 7448640412 is a through-hole common mode choke from the WE-FC series. It features a frame core design with an inductance of 3.9 mH to 5 mH and a rated DC current of 1 A to 1.25 A. The component has a typical DC resistance (DCR) of 270 mOhm to 310 mOhm per line. It is designed for two-line applications and operates effectively at 10 kHz.

Feature Summary

Frame core construction for high magnetic efficiency
Through-hole mounting for robust mechanical stability
Current-compensated design for noise suppression

Applications

Mains operated LED drivers
Electronic ballasts
Switched-mode power supplies
Lighting equipment

Procurement Notes

Verify the specific datasheet version, as some sources list 3.9 mH while others indicate 5 mH. Confirm the exact DCR value (270 mOhm vs 310 mOhm) and current rating (1 A vs 1.25 A) required for your circuit design before ordering. Ensure the through-hole footprint matches your PCB layout constraints.

Selection Notes

Select this component when a through-hole common mode choke is required for mains-operated equipment. The WE-FC series offers a balance of inductance and current handling suitable for general electronic equipment. Consider the physical size and lead spacing if space is limited on the printed circuit board.

Part Context

This part belongs to the Würth Elektronik WE-FC series of common mode chokes. These components are specifically engineered for filtering electromagnetic interference in power lines. The series utilizes a frame core technology to provide consistent performance across various industrial and consumer electronics applications.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Verify compatibility with existing designs by matching inductance, current rating, and physical dimensions before considering alternative components.
