7448640401

Overview

The Würth Elektronik 7448640401 is a current-compensated common mode choke from the WE-FC series, designed for power line filtering. It features through-hole radial mounting with an inductance of 6.8 mH measured at 10 kHz. The component supports a maximum DC current of 800 mA and exhibits a typical DC resistance of 480 mOhms. It operates within a temperature range of -40°C to +125°C.

Feature Summary

Current-compensated design providing roughly twice the leakage inductance compared to comparable toroidal chokes
AEC-Q200 qualified for automotive reliability standards
Radial through-hole termination for PCB integration

Applications

Automotive power line filtering
Common mode noise suppression in electronic circuits
EMI reduction in power supply inputs

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the AEC-Q200 qualification meets the specific requirements of the target application environment. Ensure the through-hole footprint dimensions align with the printed circuit board layout constraints.

Selection Notes

Select this component when higher leakage inductance is required relative to standard toroidal designs. The 6.8 mH value suits applications needing significant common mode attenuation at lower frequencies. Verify that the 800 mA current rating accommodates the peak load currents without saturation. Consider the physical size and lead spacing for assembly compatibility.

Part Context

This part belongs to the WE-FC series of current-compensated chokes manufactured by Würth Elektronik. These components are engineered to offer enhanced performance over traditional toroidal solutions by doubling the leakage inductance. The series is specifically targeted at automotive and industrial applications requiring robust EMI filtering capabilities.
