LAN1VSOQ40351C1

Overview

The LAN1VSOQ40351C1 is a 100BASE-T LAN transformer manufactured by Eaton Electronics. It features an inductance of 350uH and supports quad port configurations with 40 pins. The component provides 1500Vac isolation and utilizes an open header design. It is specified for non-PoE applications within Ethernet network infrastructure.

Feature Summary

• Supports 100BASE-T Ethernet standards
• Quad port configuration for multi-line connectivity
• High voltage isolation capability

Applications

• Ethernet network interface circuits
• Computer networking hardware
• Industrial communication equipment

Procurement Notes

Verify the specific datasheet version, as documentation indicates effective dates such as October 2023. Confirm that the part number corresponds to the non-PoE variant, as similar suffixes may indicate PoE capabilities. Ensure the 40-pin open header package matches the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for standard 100Mbps Ethernet applications requiring quad port integration. The 350uH inductance value suits typical signal transformer requirements. Verify compatibility with the specific circuit topology, noting that this unit is designated for non-Power over Ethernet implementations rather than powered variants.

Part Context

This component belongs to Eaton's LAN transformer series designed for network connectivity. It serves as a pulse transformer for data transmission lines. The product line includes variations for different isolation levels and power delivery specifications, distinguishing this model as a standard data-only solution.

Replacement Considerations

Consult official Eaton documentation for direct substitutes. Similar models like LAN1VSOPQ48351C1 exist but support Power over Ethernet, which differs functionally from this non-PoE unit. Do not assume interchangeability without verifying pinout and electrical specification alignment.
