749196541

Overview

The Würth Elektronik 749196541 is a WE-FLEX flexible transformer designed for board-mount DC/DC switching converter applications. It features an inductance of 7.6 µH at 10 kHz and supports a maximum current of 2.46 A with 500 VDC isolation voltage. The component operates within a temperature range of -40°C to +125°C and utilizes a surface mount package measuring 21.00 mm x 29.70 mm.

Feature Summary

• Configurable winding structure for versatile DC/DC converter topologies
• High isolation voltage rating for safety-critical power stages
• Compact surface mount footprint optimized for dense PCB layouts

Applications

• Flexible DC/DC power supply modules
• Isolated converter designs requiring custom turns ratios
• Industrial power conversion systems

Procurement Notes

Verify the specific datasheet revision and electrical tolerances against your design requirements before ordering. Confirm that the surface mount footprint dimensions align precisely with your PCB layout constraints. Ensure the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when a standard fixed-ratio transformer does not meet the specific voltage or current requirements of your DC/DC topology. The flexible design allows for customized winding configurations to optimize efficiency and size in isolated power applications.

Part Context

This part belongs to the WE-FLEX series from Würth Elektronik, which specializes in configurable transformers for power electronics. The series provides engineers with adaptable magnetic components to simplify the development of complex isolated power supplies without designing custom magnetics from scratch.

Replacement Considerations

Check for direct substitutes within the WE-FLEX family that share identical pinouts and core materials. Verify that any alternative maintains the same 500 VDC isolation rating and 7.6 µH inductance tolerance to ensure circuit compatibility.
