7446323004

Overview

The Würth Elektronik 7446323004 is a current-compensated common mode choke from the WE-LF series, designed for power line filtering. It features a 4 mH inductance measured at 10 kHz and supports a DC current rating of 3 A. The component has a maximum DC resistance of 0.07 ohms and operates within a temperature range of -40°C to 125°C. Packaged for through-hole mounting, it provides effective noise suppression for two-line applications in general electronic equipment.

Feature Summary

Current-compensated design for efficient magnetic flux cancellation
Through-hole construction for robust mechanical mounting
Wide operating temperature range suitable for diverse environments

Applications

Power line filtering in general electronic equipment
Noise suppression for two-line AC/DC circuits
EMI reduction in consumer electronics power supplies

Procurement Notes

Verify the complete part number including any suffixes against the official Wurth Elektronik datasheet to ensure correct specifications. Confirm that the required inductance, current rating, and package type match the application needs. Check RoHS compliance status if restricted substances are a concern. Ensure the through-hole footprint aligns with the PCB layout requirements before ordering.

Selection Notes

Select this component when a high-inductance common mode choke is needed for low-frequency noise attenuation. The 3 A current rating makes it suitable for moderate power applications. Consider the through-hole package if automated surface-mount assembly is not available or if higher mechanical strength is required for the specific installation environment.

Part Context

This component belongs to the WE-LF series of common mode chokes manufactured by Würth Elektronik. The series focuses on providing reliable filtering solutions for power lines. The 7446323004 variant specifically offers 4 mH inductance, distinguishing it from other models in the lineup that may have different inductance values or current ratings.
