Common SMD LED package size specification table


 LED lamp beads are divided into surface mount type (SMD) and direct insertion type (DIP). Surface mount is the patch that everyone often talks about, and it has also become patch type. This article mainly introduces the specifications and naming of SMD lamp beads.

 

 After a single LED is packaged, it is usually named after its size, such as: 3528, 5050, 0603, 0805, 3020, 335, 020, 3535, 3014, etc. These abbreviations also become specific specifications and models, but it should be noted that: some are imperial Yes, some are metric, and the units are not completely unified.

 

Note: 1 inch = 2.539999918 centimeters (cm), the usual method is: 1inch = 25.4 mm

 

       Combining the above table to make some simple explanations, give examples of common specifications and models of LED patches and their meanings: 0603, 0805, 3528, 5050 refer to the size of surface mount SMD LEDs, that is, the corresponding specifications.

 

      For example: 0603 refers to a length of 0.06 inches and a width of 0.03 inches. The corresponding metric system is 1608, which means that the length of the LED element is 1.6mm and the width is 0.8mm. The metric system is called 1608, and the English system is called 0603.

 

       0805 corresponds to 2012 in the metric system, which means that the length of the LED element is 2.0mm and the width is 1.2mm. The metric system is called 2012, and the English system is called 0805. But note that the 3528 and 5050 units are metric.

 

    1210: Converted to metric system is 3528, which means that the length of the LED element is 3.5mm and the width is 2.8mm. The industry abbreviation is 3528, and the English name is 1210.

 

    3528: This is called the metric system, that is, the length of the LED component after packaging is 3.5mm and the width is 2.8mm. The industry abbreviation is 3528.

 

    5050: This is called the metric system, that is, the length of the LED component after packaging is 5.0mm, and the width is 5.0mm. The industry abbreviation is 5050.
