Pulse Transformers Procurement Notes

Verify that the procurement source explicitly confirms the part number 750031353 matches the Würth Elektronik specification for Single Pair Ethernet transformers. Ensure the component is compatible with the required SI3210 or SI3211SMD chipset integration. Confirm RoHS3 compliance status and check for any recent Product Change Notifications regarding packaging or design updates before finalizing orders.

Pulse Transformers Selection Notes

Select this component when designing circuits requiring Single Pair Ethernet connectivity with integrated power delivery capabilities. The 1500Vrms isolation rating makes it suitable for applications demanding robust electrical separation between network lines and power domains. Ensure the PCB layout accommodates the surface-mount package dimensions and thermal requirements for 200kHz operation.

Pulse Transformers Part Context

This component belongs to the Würth Elektronik portfolio of Ethernet solutions, specifically targeting modern low-pin-count networking standards. It serves as a critical passive element in enabling data and power transmission over single twisted pairs, facilitating compact device designs in industrial and consumer electronics sectors.

Pulse Transformers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other SPE transformers only if they explicitly support the same SI3210/SI3211SMD chipsets and meet the 1500Vrms isolation requirement.
