3D Model Datasheet

WA8704-ALD

PoE Signal Path Transformer

Exceeds the return loss requirements of Gbit Ethernet
Designed to meet upcoming IEEE802.3bt high power PoE standard
Designed for 150 W 4-pair signal path with 1.5 A on each center tap.
1.5 A DC current applied to each cable side center tap causes a 15°C rise from 25°C ambient.
This is for reference only and does not represent absolute maximum ratings.
