Product Overview
The B1608S is a single-port 10/100M POE+ transformer module designed for Ethernet applications. It is compatible with various 10/100 Base-TX transceivers requiring a 1:1 transmit and receive turns ratio and complies with the IEEE 802.3at standard. Featuring a low-profile surface mount package suitable for Hi-Temp Reflow processes, this module offers a single-channel interface with tuned Common Mode Chokes (CMCs) to enhance EMC system performance. It is suitable for both End-span and Mid-span POE+ applications, providing a 720mA current capability per POE port. The module operates within a wide temperature range of -40 to +85.
