Overview

The Würth Elektronik 744253101 is a surface-mount common mode line filter from the WE-SL3 series. It features an inductance of 100 µH and an impedance of 5 kΩ at 1 kHz. The component supports a maximum DC current of 450 mA with a maximum DC resistance of 0.45 Ω. Designed for operation between -40 °C and +125 °C, it utilizes a compact SMD package measuring 9.2 mm x 6.6 mm x 2.5 mm. The device complies with RoHS and REACH standards.

Feature Summary

Provides effective common mode noise suppression for signal lines
Utilizes a compact surface-mount design for automated assembly
Operates reliably across a wide industrial temperature range

Applications

General electronic equipment signal filtering
Industrial control system interface protection
Consumer electronics data line noise reduction

Procurement Notes

Verify the specific part number against official Wurth Elektronik documentation to ensure accuracy. Confirm that the required electrical parameters, including inductance and current ratings, align with the target circuit design. Check for compliance certifications such as RoHS and REACH if mandated by the end product regulations. Ensure the surface-mount footprint dimensions match the PCB layout constraints.

Selection Notes

Select this component when a low-profile common mode choke is required for space-constrained designs. The 100 µH inductance offers balanced filtering performance for moderate noise environments. Consider the 450 mA current rating to ensure the component does not saturate under normal operating conditions. The wide temperature range makes it suitable for applications subject to thermal variation.

Part Context

This component belongs to the WE-SL3 series of surface-mount common mode filters. The series is characterized by its small form factor and high reliability for general electronic applications. It serves as a passive electromagnetic interference suppression solution for single-channel lines.
