744272392

Overview

The Würth Elektronik 744272392 is a surface-mount common mode choke from the WE-SL5 series, designed for signal line filtering. It features an inductance of 3.9 mH at 100 kHz and offers an impedance of 9.6 kOhms at 3 MHz. The component supports a rated current of 520 mA with a maximum DC resistance of 540 milliohms per line. It operates within a temperature range of -40°C to 125°C and utilizes a horizontal package measuring 10.00 mm x 8.70 mm x 6.50 mm.

Feature Summary

Dual-line configuration for effective common mode noise suppression in signal circuits
Ferrite core construction providing high impedance characteristics at specific frequencies
Surface-mount design optimized for automated assembly processes

Applications

Signal line filtering in electronic equipment
Common mode noise suppression in data transmission interfaces
EMI reduction in compact consumer electronics

Procurement Notes

Verify the exact part number against official manufacturer documentation to ensure correct specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for any recent product change notices regarding material composition or packaging updates. Ensure compatibility with existing PCB footprint dimensions and thermal management strategies during the sourcing phase.

Selection Notes

Select this component when high inductance values are required for low-current signal lines. The 520 mA rating suits applications with moderate current demands. Consider the physical dimensions for space-constrained designs. Evaluate the impedance profile at target noise frequencies to ensure adequate attenuation. Verify that the operating temperature range meets the environmental conditions of the final application.

Part Context

This component belongs to the WE-SL5 series of wirewound surface mount inductors. The series is characterized by ferrite cores and is intended for general-purpose filtering. The 744272392 variant specifically targets applications requiring higher inductance values compared to other members of the family. It represents a standard solution for EMI suppression in modern electronic assemblies.
