Procurement Notes

Verify the specific datasheet version corresponding to the LAN3VSO series non-PoE designation to ensure compatibility with system isolation requirements. Confirm that the 150µH inductance value aligns with the target 2.5G Base-T PHY specifications. Ensure the SMD-24 package footprint matches the PCB layout constraints. Check RoHS compliance status against current regulatory standards for the intended market.

Selection Notes

Select this component when designing systems requiring dedicated support for 2.5G Base-T speeds rather than standard 1G or 10G variants. The 150µH inductance value is critical for matching the impedance characteristics of the specific PHY transceiver. Consider the 24-pin SMD form factor for board space optimization. Evaluate the thermal performance within the -40°C to +85°C operating range to ensure reliability under varying environmental conditions.

Part Context

This part belongs to the LANxV series from Eaton Electronics, which focuses on advanced LAN transformers for modern Ethernet standards. The LAN3VSO variant specifically addresses non-PoE applications, distinguishing it from PoE-capable counterparts like the LAN3VSOP series. It serves as a passive component essential for signal coupling and common-mode noise rejection in high-speed data transmission paths.

Replacement Considerations

Cross-reference with other Eaton LAN3VSO series components for pin-compatible alternatives if different inductance values are required. Verify mechanical footprint compatibility before substituting with generic equivalents. Ensure any replacement maintains the 1500Vac isolation rating and 2.5G Base-T frequency response characteristics.
