LTC4257CDD-1#PBF Overview


The Tube package contains it.In this case, it is packaged in the same way as 8-WFDFN Exposed Pad.PoE controller type Controller (PD).Channels are growing strong/weak depending on the category: 1.In order to ensure its reliability, PoE operates at the operating temperature of 0°C~70°C.The supply voltage of this electrical Po E controller is 57V Max.A base part number LTC4257 can be used to identify its Po E controllers according to that number.A 8 termination involves terminating the transmission line with a power over ethernet controller of the same impedance as the line.It has a maximum power of 12.95W Watts.With 8 pins, it is equipped.It amounts to 3mA that the supply current is flowing.The Po E controller in question is included in the package Power Management Circuits.A transistor has a peak reflow temperature (Cel) of 260.If the maximal current (Isup) supplied for its operation reaches 3mA, it means the ethernet power controller is functioning properly.The REQUIRES A NEGATIVE SUPPLY OF 48V parameter also plays a role in it.
