Product Description
Product Overview
The QG4850S is a 2.5G POE+ Single Port Transformer Module designed for long-haul applications. It supports four pairs of category 5 UTP cable, providing isolation and low common mode emissions. This low-profile surface mount module is designed for high-temperature reflow processes and complies with IEEE 802.3bz & at standards for 2.5G Base-Z. It is engineered to support 1:1 turns ratio transceivers and can handle a maximum DC line current of 720mA at 57V.
