About SMD
SMD (Surface Mounted Diode): surface mount diodes or surface mount components are its name, SMD also has a variety of categories:
By size: 0603,0805,1210,5060,1010 and so on. Generally, SMD are diamond-shaped, so its name is based on the size L * W, the LED industry use units of inches and metric to maned the different SMDs.
The color and type of colloid are the same as common LED, only the shape of the product changed.
The following are the detailed description for these specifications:
SMD 0603 (inch): conversion to metric is 1005, means the length of LED components is 1.0mm, width 0.5mm. So by metric it is called SMD 1005, By inch, it is called SMD 0603.
SMD 0805 (inch): conversion to metric is 2125, means the length of LED components is 2.0mm, width 1.25mm. So by metric it is called SMD 2125, By inch, it is called SMD 0805.
SMD 1210 (inch): conversion to metric is 3528, means that the length of LED components is 3.5mm, width 2.8mm. So by metric it is called SMD 3528, By inch, it is called SMD 1210.
SMD 5050 (metric): This is called by the metric, means that the length of LED components is 5.0mm, width 5.0mm.
Advantages
SMD LEDs are small, solid state, high-intensity chips which when used for lighting are highly energy efficient, and deliver a vastly superior lighting experience. SMD is the latest form of packaging for LEDs or Light Emitting Diode. Also with lower light decay than strawhat and super flux LEDs.
