Wurth Elektronik WE-LAN Series LAN Ethernet Transformer, 350μH Inductance, 1:1 Turns Ratio - 7490220122


This LAN Ethernet transformer provides common-mode choking and signal coupling for network interfaces in equipment requiring power delivery over data lines. It is designed for surface mounting and supports industry Ethernet speed and PoE standards across typical industrial temperature ranges. The device's construction conforms to flame-retardant DAP black material requirements and maintains low insertion loss to preserve signal integrity in powered and unpowered links.

Features and Benefits:


• 1:1 turns ratio reduces amplitude distortion for balanced signalling
• -1dB insertion loss preserves signal fidelity at high data rates
• 350μH inductance suppresses common-mode noise on transmit pairs
• Surface-mount assembly enables Compact PCB integration
• -40 to 85°C range maintains operation in wide temperature environments

Applications


• Suitable for PoE switches complying with IEEE 802.3at requirements
• Ideal for gigabit links meeting IEEE 802.3ab specifications
• Used with legacy Fast Ethernet systems following IEEE 802.3u standards
• Can be used for PoE deployment under IEEE 802.3af power rules
• Suitable for PoE++ installations aligned to IEEE 802.3bt demands

What material standard governs the external housing?


The component uses DAP black material rated to UL94V-0 for flame retardancy.

How many isolated outputs does it provide?


It provides a single output winding suited to typical magnetics arrangements.

What is the device's performance impact on link transmission?


It exhibits an insertion loss of -1dB which minimises attenuation on Ethernet signals.

Which operating temperatures will it tolerate?


It operates between -40 to 85°C for use in varied thermal environments.
