Wurth Elektronik LAN Ethernet Transformer, 350μH Inductance, 1:1 Turns Ratio - 7499011222A

This LAN Ethernet transformer provides magnetic isolation for 10/100Base Ethernet links in through‑hole PCB assemblies. It is designed to operate across a wide frequency range suitable for network signalling and to perform within typical temperature environments encountered in industrial and commercial electronics.

Features and Benefits:

• 1:1 turns ratio provides signal symmetry and straightforward interface
• 350μH inductance supports magnetics for balanced transmission
• 1MHz to 100MHz bandwidth handles Ethernet signalling frequencies
• Low insertion loss -1dB preserves signal integrity during transmission
• RoHS‑compliant construction reduces restricted‑substance concerns

Applications

• Suitable for coupling 10/100Base Ethernet ports on motherboards
• Ideal for through‑hole PCB Ethernet transformer implementations
• Used where isolation is required in industrial network Interfaces
• Can be used for magnetic coupling in network Interface modules

What operating temperature range does it support?

It operates between -40°C and 85°C, allowing use across typical industrial temperature conditions.

How many outputs does the component present for network connections?

It provides a single output configured for standard Ethernet coupling.

What mounting method is required for board assembly?

The device is intended for through‑hole mounting suitable for soldered PCB installation.

Which Ethernet standards are supported by this transformer?

It is compatible with 10/100Base Ethernet signalling.
