Overview

The Würth Elektronik 749196531 is a surface-mount flexible transformer from the WE-FLEX series, designed for configurable DC/DC switching mode power supplies. It features an air gap construction with a primary inductance of 9.7µH and supports a maximum current of 1.7A. The component provides 500VDC isolation and operates within a standard temperature range.

Feature Summary

Flexible core construction allows for custom winding configurations to meet specific design requirements.
Integrated air gap ensures stable inductance performance under varying load conditions.
Surface-mount package facilitates automated assembly and compact PCB layout.

Applications

Configurable DC/DC converter modules
Isolated power supply designs
Telecommunications equipment

Procurement Notes

Verify the specific datasheet version for precise electrical tolerances and thermal derating curves before finalizing the design. Confirm that the 1.7A current rating aligns with the peak and RMS requirements of the target application circuit to ensure long-term reliability.

Selection Notes

Select this component when a customizable magnetic solution is required for isolated power architectures. The flexible nature allows engineers to optimize turns ratio and leakage inductance. Ensure the PCB footprint matches the SMD dimensions specified in the official mechanical drawing.

Part Context

This part belongs to the WE-FLEX family of flexible transformers manufactured by Würth Elektronik. These components are engineered for high-frequency applications where standard fixed transformers lack the necessary customization flexibility for unique power conversion topologies.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 9.7µH inductance, 1.7A current rating, and 500VDC isolation voltage specifications exactly.
