Coilcraft ETH1-xL Signal Path Transformers
Coilcraft ETH1-xL Signal Path Transformers are developed to meet Power over Ethernet (PoE) IEEE 802.3at-2009 and IEEE 802.3bt Type 4 standards for PoE+ and PoE++ applications. The ETH1-460L transformers are designed for four-pair cabling plants at 60W/120W. The ETH1-230L transformers are designed for two-pair cabling plants at 30W/60W, and two modules are used for four-pair cabling in 30W/60W applications. Coilcraft ETH1-xL Signal Path Transformers operate in an ambient temperature range of -40°C to +85°C.
