Wurth Elektronik LAN Ethernet Transformer, 350μH Inductance, 1:1 Turns Ratio - 749012011

This LAN Ethernet transformer provides galvanic isolation and signal coupling for Ethernet networks while supporting Power over Ethernet applications. It is a surface-mounted component designed to integrate into network Interface modules, handling typical LAN signalling with low insertion loss and operating across a wide temperature range.

Features and Benefits:

• 1500V AC isolation protects downstream circuitry
• 350μH inductance improves common-mode noise suppression
• 1:1 turns ratio preserves signal amplitude and integrity
• -1dB insertion loss minimises signal attenuation
• Solder termination enables stable board attachment

Applications

• Suitable for PoE implementations complying with IEEE 802.3at
• Used with single-output port Ethernet interfaces
• Ideal for Compact surface-mounted network modules
• Can be used for isolation in industrial LAN equipment
• Suitable for systems requiring flame-retardant components

What temperature range can it operate within?

The component is specified to function between -40°C and 85°C.

What approvals cover material and electrical safety?

It meets RoHS and UL94V-0 material flammability standards and aligns with IEEE 802.3at for PoE use.

How is the part terminated for PCB assembly?

Electrical connection is via solder termination intended for surface mounting.

How many outputs does the device provide?

The device offers a single output for Ethernet isolation.

What are the physical footprint dimensions?

The package measures 12.7mm in length, 9.52mm in width and 5.8mm in depth.
