Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape and reel dimensions. Confirm that the requested quantity aligns with manufacturer standard pack sizes to avoid partial reel handling issues. Check for recent Product Change Notifications regarding labeling or minor specification updates. Ensure storage conditions comply with moisture sensitivity level requirements before reflow soldering. Validate compatibility with intended PCB footprint using official CAD models.

Selection Notes

Select this component when designing systems requiring isolated power delivery over Ethernet cabling. The 1500Vrms isolation rating supports stringent safety standards for industrial and commercial installations. Consider the 200-500kHz operating range when designing magnetic components and control loops. The 36-57V primary input range matches standard PoE voltage classifications. Evaluate thermal performance based on the surface-mount package constraints.

Part Context

This transformer is part of Würth Elektronik's WE-PoE product line, which focuses on integrated solutions for Ethernet-powered devices.
