Switching Converter, SMPS Transformers Procurement Notes

Verify that the specific part number matches the design requirement for the LT8304 controller, as this transformer is tuned for that specific application. Confirm that the PCB footprint accommodates the specified dimensions of 13.46mm x 17.75mm. Ensure thermal management strategies account for the 125°C maximum operating temperature. Check for any recent Product Change Notifications regarding packaging or marking updates before finalizing orders.

Switching Converter, SMPS Transformers Selection Notes

Select this component only when designing around the LT8304 flyback controller, as it is not a generic transformer. The 40µH inductance value is critical for the intended switching frequency range of 50-200kHz. Consider the 1500Vrms isolation rating if high-voltage separation is required between primary and secondary sides. The surface-mount package requires appropriate reflow soldering profiles suitable for components up to 12.70mm in height.

Switching Converter, SMPS Transformers Part Context

This component belongs to the WE-FB series, specifically the MID-FLYLT sub-series, which targets mid-power applications. It is part of Würth Elektronik's portfolio of transformers designed to simplify power supply development by providing pre-tuned magnetic components for popular controller ICs. This reduces design time and ensures performance consistency for engineers using standardized topologies.

Switching Converter, SMPS Transformers Replacement Considerations

No direct public substitute part numbers are documented for this specific configuration. Due to its optimization for the LT8304 controller and specific 40µH inductance, alternative flyback transformers must be carefully evaluated for compatibility with the control loop and magnetic requirements.
