744207

Overview

The Würth Elektronik 744207 is a surface-mount common mode line filter belonging to the WE-SL series. It features an inductance of 35 µH at a test frequency of 100 kHz and supports a maximum DC current of 2.7 A. The component exhibits a maximum DC resistance of 35 mΩ and an impedance of 1.1 kΩ with a tolerance of 35%. Designed for PCB mounting, it operates within a temperature range of -40°C to +125°C. The physical dimensions are 13.3 mm x 10.2 mm x 4.7 mm, and it is supplied in reel, cut tape, or MouseReel packaging formats.

Feature Summary

Provides effective noise suppression for differential signal lines through common mode filtering capabilities.
Utilizes a compact surface mount design suitable for automated PCB assembly processes.
Constructed as an unshielded component to minimize size while maintaining specified electrical performance.

Applications

Signal line filtering in electronic circuits
Noise suppression in differential data transmission interfaces
Common mode interference reduction in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging configuration, such as reel or cut tape options. Confirm that the selected variant meets all required environmental certifications, including RoHS and REACH compliance standards. Cross-reference the part number with official Wurth Elektronik documentation to validate technical specifications before finalizing procurement orders.

Selection Notes

Select this component when a 35 µH inductance value is required for common mode noise attenuation in high-current applications up to 2.7 A. Ensure the PCB layout accommodates the 13.3 mm x 10.2 mm footprint and verify thermal management requirements for operation within the -40°C to +125°C range. Consider the unshielded construction when assessing electromagnetic interference interactions with adjacent circuitry.

Part Context

This component is part of the WE-SL series from Wurth Elektronik, which specializes in surface mount common mode chokes. The series is engineered for signal line protection and noise filtering in various electronic systems. The 744207 specifically addresses applications requiring moderate inductance values with high current handling capabilities in a compact form factor.

Replacement Considerations

Consult the official Wurth Elektronik cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence based solely on similar inductance or current ratings without validating impedance characteristics and physical dimensions against the original specification sheet.
