Abracon ALANS100X1 LAN Transformer Modules

Abracon ALANS100X1 LAN Transformer Modules are designed to be compatible with 10 BASE-T and 100 BASE-TX single port SMD LAN. These transformer modules feature high-performance magnetics for EMI suppression and common mode noise rejection. The ALANS100X1 operates at -55°C to +125°C temperature range. These transformer modules are ideal for use in fast Ethernet, servers, switches, routers, access points, broadcast video, and set-top box.
