Procurement Notes

Verify the specific suffix designation against official documentation to confirm functional characteristics, as ordering suffixes may alter specifications. Ensure compatibility with the target PCB footprint and reflow profile requirements. Confirm that the selected variant meets the necessary isolation voltage and inductance parameters for the intended 100BaseTX application design.

Selection Notes

Select this component for designs requiring isolated LAN transformers without PoE capabilities. The single-channel configuration suits standard Ethernet port implementations. Consider the surface mount package type for automated assembly processes. Verify that the unshielded construction aligns with the electromagnetic interference requirements of the final system environment.
