750318938

Overview

The Würth Elektronik part number 750318938 is a WE-PoE++ Power over Ethernet Plus Plus Transformer designed for board mounting. It functions as a transformer for DC/DC converters and Switching Mode Power Supplies (SMPS). The component features 1500Vrms isolation voltage and supports operation up to 250kHz. It utilizes the EFD2 core geometry and is rated for 60W power applications. The device employs Surface Mount Technology (SMT) for integration into electronic circuits.

Feature Summary

• Provides high-voltage isolation of 1500Vrms between primary and secondary sides
• Optimized for Power over Ethernet (PoE++) applications in DC/DC converters
• Supports switching frequencies up to 250kHz for efficient energy transfer
• Designed with EFD2 core geometry for compact surface mount integration

Applications

• Power Over Ethernet (PoE) systems
• DC/DC converter circuits
• Switching Mode Power Supply (SMPS) designs

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be updated. Confirm that the EFD2 package style matches your PCB footprint requirements. Ensure the 1500Vrms isolation rating meets the safety standards of your target equipment. Cross-reference the 60W power handling capability with your thermal design constraints before finalizing procurement.

Selection Notes

Select this component when designing PoE++ powered devices requiring robust galvanic isolation. The 250kHz frequency range suits modern high-efficiency SMPS topologies. Consider the SMT form factor for automated assembly processes. Verify compatibility with TPS23730 or similar controllers if referenced in system schematics. Ensure the EFD2 size fits within the available board area constraints.
