Surface Mount Sizes rectangular components
These are mainly resistors and capacitors which are the most common components used.
| SMD Package Number | Length x Width mm |
Length x Width inches |
|---|---|---|
| 1812 | 4.6 x 3.0 | 0.18 x 0.12 |
| 1206 | 3.0 x 1.5 | 0.12 x 0.06 |
| 0805 | 2.0 x 1.3 | 0.08 x 0.05 |
| 0603 | 1.5 x 0.8 | 0.06 x 0.03 |
| 0402 | 1.0 x 0.5 | 0.04 x 0.02 |
| 0201 | 0.6 x 0.3 | 0.02 x 0.01 |
Of these sizes, the 1812, and 1206 sizes are now only used for applications requiring larger levels of power.
The 0603 and 0402 SMT sizes are currently the most widely used.
