SOT-223 (Small Outline Transistor) - (for high powered devices, 6.7 x 3.7 x 1.8Mmm.

SOT-23 (Small Outline Transistor) - (3 leads for diodes or transistors, but some ICs can come in this form factor too, and have more pins.

Even though a diode only requires two leads, they are given three so they can be oriented properly. Transistors and diodes are usually packaged the same way.

For this reason, 0603 components are the smallest recommended components for hand soldered board designs. When choosing components that will be hand soldered, anything smaller than 0603 can be very difficult to handle. Note that sizes 18 imperial are specialized sizes, most commonly used for components that high heat dissipation requirements.ДЄlso note that smaller components tend to be cheaper. The following chart illustrates the actual size of components in relation to their size code: sizes This is especially important for codes such as 04, which are found in both imperial and metric, but specify different sizes. When purchasing components by their size code, itвЂ™s important to know whether or not the size specified is in imperial or metric.

The metric equivalent of 0402 is 1005, which is 1.0mm x 0.5mm.

Their size is specified by a size code which is their width x height.ДЇor instance, the imperial size code of 0402 specifies that the component is 0.04' x 0.02'. Common Passive Rectangular ComponentsД¬ommon passive rectangular components include things like resistors and capacitors. Surface mount component standards are specified by the Joint Electron Device Engineering Council (JEDEC) Solid State Technology Association ( ).
