SMT components of Resistors and Capacitors

These SMT components are mainly resistors and capacitors which form the bulk of the number of components used. There are several different sizes which have been reduced as technology has enabled smaller components to be manufactured and used.

Package type Dimensions mm Dimensions Imches
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 specialized components or ones requiring larger levels of power to be dissipated The 0603 and 0402 SMT sizes are the most widely used.
