The EP13 Power over Ethernet Plus (PoE+) Transformer is developed for compact Ethernet devices requiring both stable power delivery and high-speed data transmission. Featuring an EP13 ferrite core structure, it provides optimized signal coupling, reliable isolation, and efficient power transfer for modern PoE+ networking systems.
Compared with larger PoE transformer solutions, the EP13 design emphasizes miniaturization and integration flexibility, making it suitable for compact communication devices and space-sensitive PCB layouts.
It supports PoE+ applications compliant with IEEE 802.3at standards and is widely used in IP cameras, wireless networking equipment, smart IoT terminals, and compact Ethernet-powered systems.
Custom winding structures, turns ratios, and mounting configurations are available to match different network power architectures.
