Product Overview
The B4004S is a 10/100M POE Quad Port Transformer Module designed for compatibility with various 10/100 Base-TX transceivers requiring a 1:1 transmit and receive turns ratio. It complies with the IEEE 802.3af standard, including baseline wander compensation. This module features a low-profile surface mount packaging suitable for Hi-Temp Reflow Processes and offers various pinout options for optimal printed board layout. It is suitable for both End-span and Mid-span POE applications, providing 350mA current capability per POE port. The operating temperature range is -40 to +85, and the storage temperature range is -40 to +125.
