749196341

Overview

The Würth Elektronik part number 749196341 is a surface-mount DC/DC transformer belonging to the WE-FLEX series. It features an air gap design and provides 500VDC isolation. The component has a nominal inductance of 7.9uH (with some sources citing 7.3uH) and a current rating of approximately 0.97A to 1.33A. It utilizes a 1:1:1:1:1:1 winding configuration, making it suitable for configurable power supply applications.

Feature Summary

• Flexible design for configurable DC/DC switching converter topologies
• Integrated air gap for enhanced energy storage capabilities
• High voltage isolation rated at 500VDC
• Surface mount package for automated PCB assembly

Applications

• Isolated DC/DC converter modules
• Multi-output power supply designs
• Industrial control system power stages
• Configurable switching mode power supplies

Procurement Notes

Verify the specific datasheet version when ordering, as inductance values may vary slightly between 7.3uH and 7.9uH depending on the manufacturing batch or documentation revision. Ensure the footprint matches the WE-FLEX series specifications. Confirm that the 500VDC isolation rating meets the safety requirements of the target application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring high isolation voltage in a compact surface-mount form factor. The flexible winding ratio supports various isolated converter architectures. Engineers should verify thermal performance under maximum load conditions and ensure the core material handles the expected flux density without saturation. Compare against standard transformers if higher current ratings are required.

Part Context

This component is part of Würth Elektronik's WE-FLEX line, which specializes in flexible magnetic components for power electronics. The series is designed to support complex power conversion needs in industrial and communication infrastructure. These transformers bridge passive components and intelligent power systems, enabling efficient energy transfer in modern electronic devices.

Replacement Considerations

Direct substitutes must match the 500VDC isolation, SMD package, and similar inductance range. Check manufacturer cross-reference lists for equivalent WE-FLEX variants with adjusted current ratings. Ensure any replacement maintains the same pinout and mechanical dimensions to avoid PCB redesign.
