Product Description

Product Overview

The B1605S 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. This module complies with the IEEE 802.3at standard, featuring baseline wander compensation and POE+ 720mA cable interface for isolation and low common mode emissions. Its low-profile surface mount packaging is suitable for Hi-Temp Reflow processes, and it incorporates CMCs tuned to enhance EMC system performance. The operating temperature range is -40 to +85.
