Procurement Notes
Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure correct component identification. Confirm that the required electrical parameters, such as inductance and isolation voltage, match the design specifications. Check for any recent product change notices or obsolescence announcements directly from the manufacturer before finalizing procurement decisions.
Selection Notes
Select this component when a flexible transformer solution is required for isolated DC/DC conversion. Ensure the PCB layout accommodates the specified footprint dimensions of 22.10mm by 17.50mm. Verify that the thermal management strategy supports operation up to 125°C ambient temperature. Confirm compatibility with surface mount assembly processes.
Part Context
This component belongs to the WE-FLEX series of transformers manufactured by Würth Elektronik. The series is characterized by flexible core materials intended for space-constrained power electronics. These components are distinct from rigid core transformers and are optimized for high-frequency switching applications requiring galvanic isolation.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided source material. Consult official Wurth Elektronik documentation for potential cross-references or updated series replacements.
