LTC4278IDKD Product Details
LTC4278IDKD Overview
The Tube package contains it.It is packaged in a way that resembles 32-WFDFN Exposed Pad.PoE controller type Controller (PD), DC/DC.There is an increase in the number of channels strong/weak as follows: 1.In order to maintain reliability, PoE operates at a temperature of -40°C~85°C.Electrical Po E controller 37.2V~60V has a 37.2V~60V supply voltage.There are 32 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 25.5W Watts that can be generated by this electrical ethernet over power controller.There is a pin count of 32 on this ethernet over power controller.There is a current of supply amounting to 1.35mA Max.There is a Po E controller named Switching Regulator or Controllers that includes this Po E controller.During the reflow process of this electrical ethernet power controller, Cel (peak reflow temperature) reaches 260.Its maximum input voltage is 20V.In order for this power over ethernet devices to function properly, it requires a minimal input voltage of 4.5V.
