LTC4257IS8-1#TRPBF Overview

PoE controller is part of the Tape & Reel (TR) package, which is included in the download.It is the way it is packaged that makes it 8-SOIC (0.154, 3.90mm Width).PoE controller type Controller (PD).Channels are growing strong/weak depending on the category: 1.As a precaution, the operating temperature of this Po E controller is kept at -40°C~85°C in order to maintain its reliability.This electrical Po E controller requires a voltage supply of 57V Max to operate.A part number's Po E controllers of LTC4257 can be determined by its base number.There are 8 terminations, which are the practice of ending a transmission line with a power over ethernet controller that matches the characteristic impedance of the line.There is a maximum power of 12.95W Watts that can be generated by this electrical ethernet over power controller.It is equipped with 8 pin count.The supply current amounts to 3mA.A transistor has a peak reflow temperature (Cel) of 260.In addition, it is characterized by the letter REQUIRES A NEGATIVE SUPPLY OF 48V.
