Common SMD Part Sizes

The table provides the common dimensions for both SMD resistor chip and capacitor chip packages.

Some chip styles, such as, Low Inductance Chip Capacitors move the terminals to the long side of the body.
However this alternate style is still some what uncommon, as compared to this orientation.

Design Notes;
The physical size for chip resistors and capacitors is shown in the graphic above.
The standard EIA component designations are shown under the type heading.
The common values for capacitors or standard wattage size for resistors are shown for each EIA component type.
The smaller the physical part, the lower the inductance.
Pick the smallest possible package size which still meets the design criteria.
The table provides dimensions in mm, the 'Type' is the English designation.
The 'type' used above are different for metric designations.
Also, there is an additional designation for Tantalum capacitors [shown above].


Case codes include:
... P ..... 0805
... A ..... 1206
... B ..... 1411
... C ..... 2412
... D/E . 2917

Note that military specifications do not use the EIA component size designation.
For example a military specification tantalum capacitor is shown below the size is CWR09.
