LTC4257CS8-1#PBF Overview

Embedded in the Tube package, it is used by many applications.In this case, it is packaged in the same way as 8-SOIC (0.154, 3.90mm Width).Controller (PD) is the type of PoE controller that this is.It has been reported that the number of channels is growing strongly/weakly: 1.In order to ensure its reliability, PoE operates at the operating temperature of 0°C~70°C.This electrical Po E controller requires a voltage supply of 57V Max to operate.It is possible to find the Po E controllers of the base part number by using the base part number LTC4257.8 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.It is estimated that this electrical ethernet over power controller has a maximum power of 12.95W Watts.In addition, it is equipped with a 8 pin count.There is a supply current of 3mA in the system.There is a Po E controller named Power Management Circuits that includes this Po E controller.There is a certain temperature that this electrical ethernet power controller reaches during reflow (Cel) of 260.It reaches 3mA when the maximal current (Isup) supplied for it to operate is reached.There is also a characteristic REQUIRES A NEGATIVE SUPPLY OF 48V associated with it.
