Ethernet Transformers

HALO Electronics Ethernet Transformers are SMD communication magnetic transformers that range from 10Mbit/s to 10G. Isolation modules are available for data only or data with PoE, PoE+, and higher power PoE requirements. These products are recognized by UL/EN60950 and DEMKO. HALO's patented SMD construction, designs and automated manufacturing processes ensure quality and reliability.
