10/100BASE-TX Ethernet Transformers

HALO Electronics 10/100BASE-TX Ethernet Transformers include single port, dual port, and quad-port isolation modules. The Ultra™ series transformers feature a smaller footprint than the industry standard for single port applications. Dual port and quad port solutions are also available in industry-standard packages.
