High-Density 1Gigabit PoE/PoE+ SMD Transformers

Pulse Electronics High-Density 1Gigabit PoE/PoE+ SMD Transformers offer less than 140mm²/port density and feature a reliable surface mount Ball Grid Array (BGA). These transformers support 4-pair PoE+ (70W) of DC power and are designed to fit behind 2xN connectors. The 1Gigabit PoE/PoE+ SMD transformers offer 10/100/1000base-T connectivity and a modular construction that exceeds IEEE802.3u/ab. These transformers operate over the -40°C to 85°C temperature range.
