Wurth Elektronik WE-STST Series LAN Ethernet Transformer, 350μH Inductance, 1:1 Turns Ratio - 74930000

This LAN Ethernet transformer provides galvanic isolation and signal coupling for Ethernet interfaces in surface-mounted assemblies. It is specified for single-output use and designed to perform across a wide operating temperature range while meeting RoHS environmental restrictions. The component is suited to applications requiring Compact magnetics with low insertion loss and standard 1:1 transmission characteristics.

Features and Benefits:

• 350μH inductance offering improved common-mode suppression
• 1:1 turns ratio ensuring symmetrical signal coupling
• -1dB insertion loss enabling efficient signal transfer
• Single-output configuration simplifying board integration
• RoHS‑approved construction supporting environmental requirements

Applications

• Suitable for industrial Ethernet nodes operating at varied temperatures
• Ideal for Compact network Interface modules requiring low loss
• Used with surface-mounted assemblies where PCB space is limited
• Can be used for isolation in single‑port Ethernet equipment
• Suitable for ruggedised communication devices requiring compliance

What operating temperature range can it withstand?

It operates between -40°C and 105°C.

How is it mounted on a board?

It is designed for surface‑mount installation.

What insertion loss performance should be expected?

Typical insertion loss is -1dB.

Does it provide multiple outputs for port aggregation?

No, it offers a single output only.

Are there any conformity statements regarding materials?

It complies with RoHS material restrictions.
