Overview

The Würth Elektronik 7448640417 is a through-hole common mode choke from the WE-FC series, designed for power line filtering. It features an inductance of 22 mH and a maximum DC current rating of 400 mA. The component has a maximum DC resistance of 1.635 ohms and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 21.2 mm in length, 16.6 mm in width, and 22.5 mm in height.

Feature Summary

Current compensated design providing approximately twice the leakage inductance compared to comparable toroidal chokes
AEC-Q200 qualified for automotive reliability standards
Radial leaded construction suitable for PCB mounting

Applications

General electronic equipment power line filtering
Automotive electronics applications requiring AEC-Q200 compliance
Common mode noise suppression in power circuits

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may undergo updates. Confirm that the radial package dimensions and lead configuration match your PCB layout requirements. Ensure the 400 mA current rating meets the operational demands of your circuit to prevent saturation or excessive heating during use.

Selection Notes

Select this component when high leakage inductance is required for effective common mode noise attenuation in space-constrained designs. The AEC-Q200 qualification makes it suitable for automotive environments where robustness is critical. Compare its 22 mH inductance against other WE-FC variants if different filtering characteristics are needed for specific frequency ranges.

Part Context

This part belongs to the WE-FC series of common mode chokes manufactured by Würth Elektronik. The series is characterized by its current-compensated structure, which enhances performance relative to traditional toroidal designs. These components are intended for general electronic equipment and automotive applications, offering reliable noise suppression in power lines.
