LTC4257IS8#PBF Overview

It is embedded in the Tube package.In other words, 8-SOIC (0.154, 3.90mm Width) refers to the way in which it is packaged.PoE controller type Controller (PD).The number of channels is growing strong/weak: 1.In order to maintain reliability, PoE operates at a temperature of -40°C~85°C.A 57V Max voltage is used to supply power to this electrical Po E controller.An associated part can be established based on the base part number LTC4257.A 8 termination involves terminating a transmission line with a power over ethernet controller whose characteristic impedance matches the line's.It is capable of producing 12.95W Watts of power at its maximum.As you can see from the image, it is equipped with 8 pin count.Current supplied to the load equals 3mA.During reflowing of the electrical ethernet power controller, the peak temperature (Cel) reaches 260 °C.
