Wurth Elektronik WE-LAN Series LAN Ethernet Transformer, 120μH Inductance, 1:1 Turns Ratio - 7490120110

This LAN Ethernet transformer provides galvanic isolation and signal coupling for 10/100 Base‑T networks in surface‑mount assemblies. It is intended for integration where isolation, constrained board space and standard Ethernet signalling between 1MHz and 100MHz are required. The component operates across a wide temperature range suitable for industrial contexts and meets recognised flammability and Ethernet power‑delivery standards.

Features and Benefits:

• 120 μH inductance reduces common‑mode noise for clearer signals
• 1:1 turns ratio maintains signal amplitude for balanced lines
• 1500 Vrms isolation protects against ground potential differences
• Insertion loss -1.0dB preserves signal integrity across the bandwidth
• Solder termination enables robust assembly for automated production

Applications

• Suitable for integrating into 10/100 Base‑T network ports
• Ideal for PoE solutions complying with IEEE 802.3at
• Used with industrial switches operating in harsh temperatures
• Can be used for board‑level isolation in LAN front‑ends
• Suitable for surface‑mount manufacturable Ethernet interfaces

What frequency range will it reliably support?

It operates from 1MHz up to 100MHz to cover common Ethernet signalling.

How does it handle thermal extremes in deployed systems?

The component is rated to function between -40°C and 85°C for varied environments.

What approvals relate to safety and Ethernet power delivery?

It carries UL94‑V0 flammability recognition and meets IEEE 802.3at requirements.

What form factor and termination does it use for PCB assembly?

It is a surface‑mount device with solder termination suited to reflow processes.
