Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the RoHS3 compliance status and MSL rating indicated in the datasheet. Check for any recent Product Change Notifications regarding marking or material updates before production integration.

Selection Notes

Select this component when designing isolated buck topologies requiring 2500Vrms isolation. Ensure the target application frequency aligns with the 300kHz operational specification. Verify that the 25µH inductance value meets the circuit design requirements at the specified test frequency of 10kHz. Confirm mechanical clearance allows for the 8.50mm maximum height.

Part Context

This transformer belongs to the MID-IBTI series by Würth Elektronik, specifically engineered for isolated DC/DC conversion. It utilizes chipset technology associated with Texas Instruments components, such as the LM5160, to facilitate efficient power transfer in regulated switching environments while maintaining strict isolation standards.

Replacement Considerations

Consult official Wurth Elektronik cross-reference lists for verified substitutes. No direct public substitute part numbers are confirmed in the provided documentation. Ensure any alternative maintains identical isolation voltage and form factor constraints.
