Wurth Elektronik WE-LAN Series LAN Ethernet Transformer, 350μH Inductance, 1:1 Turns Ratio - 749020100A

This LAN Ethernet transformer provides magnetics for network interfaces, designed for surface mounting on PCBs and intended to support signal coupling and isolation in Ethernet applications. It operates across a wide temperature span and complies with RoHS standards, making it suitable for constrained-board implementations requiring regulatory adherence.

Features and Benefits:

• 350μH inductance reduces common-mode interference and improves signal integrity
• 1:1 turns ratio maintains signal symmetry for balanced transmission
• Insertion loss -1.1dB preserves signal strength across the link
• Surface-mount format enables Compact PCB integration and automated assembly
• Operating range -40 to 105°C supports extended environmental conditions

Applications

• Suitable for integrating into switched network Interface modules
• Ideal for use in LAN port isolation on embedded systems
• Used with industrial Ethernet equipment requiring thermal tolerance
• Can be used for Compact router and hub PCB designs
• Used for modular network Interface cards in constrained layouts

What mounting method is required for installation?

It uses surface-mount placement compatible with standard PCB solder processes.

How does the device perform under elevated temperatures?

It is rated to operate continuously up to 105°C without specification changes.

What regulatory consideration affects material selection?

The component meets RoHS requirements for restricted substances.

How does the magnetics impact link attenuation?

It contributes an insertion loss of -1.1dB, indicating minimal signal attenuation.

What electrical coupling configuration is provided?

The winding arrangement presents a 1:1 turns ratio for direct balanced coupling.
