The EFD20 Power over Ethernet Plus (PoE+) Transformer is designed for 802.3at PoE systems requiring higher power delivery, stable signal integrity, and efficient electrical isolation. It supports both power transmission and data communication over a single Ethernet cable in modern network infrastructure.
Based on a compact EFD20 ferrite core structure, this transformer enables high-density PCB integration while maintaining excellent electrical performance and thermal stability under continuous PoE load conditions.
Compared with standard PoE transformers, the PoE+ version supports higher power levels, making it suitable for more demanding network-powered devices.
Customized turns ratios, power levels, insulation systems, and winding configurations are available according to application requirements.
PoE+ powered devices
