Coilcraft high power PoE (Power over Ethernet) signal path magnetics is a reference circuit design that meets the current requirement of Gigabit Ethernet PoE Plus.
This reference design is based on the HPX2126L Isolation Transformer and the HPF2187L Common Mode Choke.
The High Power POE Signal Path Magnetics design features an open circuit inductance of ≥350µH with a 38mA DC offset applied from 0°C to 70°C. This reference circuit is capable of handling 3.8A of injected current.
Applications for the high power PoE (Power over Ethernet) signal path magnetics reference circuit design include remote IoT devices such as IP security cameras, LED lighting and displays, and networking routers.
