Ethernet Magnetic Transformers Description:
The 749010012A(LP1102NL) is a 10/100 Base-T 1-port LAN Transformer.
The inductance value of 350μH Compliant with IEEE 802.3 standards.
Designed with a robust internal layout for a long life. The surface
mount design saves space on boards and requires no plug-ins or
solder installation. This Ethernet Transformer offers reliable
performance and easy integration into Ethernet devices. WE-LAN
transformers are compliant with most ICs for Ethernet applications
such as AMD, Globespan, Intel, and Realtek. It can be used for IoT,
hubs, routers, switches, and IP cameras.

Main Functions of 10/100Base-T
Transformers:
1. Impedance matching helps reduce signal reflections on the cable.
2. Electrical isolation: protects against ground loops and voltage surges.
3. Common mode noise rejection: filters out noise that appears as the same signal on both wires of
a twisted pair. This improves signal integrity.
4. Compact size: Surface mount models minimize PCB space usage.
5. Easy installation: LAN transformers are easier to install than through-hole
components.
