LTC4257IS8-1#PBF Product Details

LTC4257IS8-1#PBF Overview


Embedded in the Tube package, it is used by many applications.It is packaged in the way of 8-SOIC (0.154, 3.90mm Width).Controller (PD) is the type of PoE controller that this is.Channel growth is strong or weak: 1.PoE operates with the operating temperature of -40°C~85°C to ensure its reliability.Electrical Po E controller 57V Max has a 57V Max supply voltage.A base part number LTC4257 can be used to identify its Po E controllers according to that number.An 8 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.There is a maximum power of 12.95W Watts in this electrical ethernet over power controller.There is a pin count of 8 on this ethernet over power controller.There is a supply current of 3mA in the system.This Po E controller is included in Power Management Circuits.8 pins are used in the design of this board.There is a certain temperature that this electrical ethernet power controller reaches during reflow (Cel) of 260.It reaches 3mA when it receives the maximal current (Isup).
