SMD Package Chip Resistor Pack (SMT resistor or Chip resistor) of 0805 packages is a rectangular-shaped SMD resistor. 0805 SMD package is correlated with its land pattern in inches. Here, 0805 SMD, the “08” means it is 0.08 inches in length and the “05” means it is 0.05 inches in width. So the dimension of 0805 SMD is .08” x .05”(2.0mm x 1.3mm). It is having a metallic area on both sides of the ceramic body and that metallic end is placed to PCB where it has a pad and is soldered. If you want to make your PCB size so small as possible then undoubtedly go for SMD.
