    Products Detail

    STHS4257A1M6F Overview


    There is an embedded version of it in the Tape & Reel (TR) package.In other words, 8-SOIC (0.154, 3.90mm Width) refers to the way in which it is packaged.I would like to inform you that this PoE controller is of the Controller (PD) type.Channels are growing strong/weak depending on the category: 1.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~85°C.There is a voltage of 57V Max that is used for the supply voltage of this electrical Po E controller.A base part number STHS4257 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 that can be generated by this electrical ethernet over power controller.There is a pin count of 8 on this ethernet over power controller.330?A is the amount of supply current that is available.There are 8 pins on the board that are designed for it.In this case, it is mounted in the direction of Surface Mount.
