Decoding the SMD LED
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.
