The 11FB-05NL is a surface-mount LAN pulse transformer designed for 10/100BASE-T Ethernet applications, providing galvanic isolation, impedance matching, and EMI suppression for Ethernet PHY interfaces.
It integrates a 1:1 turns ratio transformer with high common-mode rejection, enabling stable signal integrity, reduced electromagnetic interference, and reliable data transmission in compact PCB designs. With 1500 Vrms isolation, wide -40°C to +85°C operating temperature, and compact SMD-16P footprint, it is well suited for network switches, routers, IP cameras, industrial Ethernet, and embedded networking devices.
