Switching Converter, SMPS Transformers Procurement Notes

Verify the exact datasheet version when sourcing this component, as manufacturers may update pinout or mechanical dimensions without changing the base part number. Confirm that the supplier provides the original Wurth Elektronik documentation to ensure compliance with the specified 5000V isolation rating and 400kHz frequency limit. Cross-reference the marking code '750343341' on the physical device against official images to prevent counterfeit parts.

Switching Converter, SMPS Transformers Selection Notes

Select this transformer only if the design requires a push-pull or forward topology with SMT assembly. Ensure the PCB layout supports the specific footprint associated with the TOR4.3/2.8/3 package. Verify that the operating environment does not exceed the thermal limits defined in the official datasheet. This component is intended for isolated power conversion; do not use it in non-isolated applications where the high isolation voltage is unnecessary or incompatible with other circuit elements.
