On Eagle, I was told that one of my parts was a 10uF cap that was of the EIA3216 package. Can I know what this is? I tried to find such a part online but was unable to do so.

  • \$\begingroup\$ I don't use Eagle, so I don't know what evil may lurk in its libraries, but it should be up to the user to determine what package he will use for a part. Perhaps the schematic library you are using has a 10 uF capacitor that specifies a 3216 package. If you can't buy a 10 uF cap in that package, or if you are making a through-hole board, you should be able to change that package to one that suits the part you intend to use. \$\endgroup\$ – Peter Bennett Oct 23 '13 at 1:27

The EIA 3216 is referring to a form factor. For example here are some form factors shown on the Wikipedia page about surface mount components:

  • EIA 3216-10: 3.2 mm × 1.6 mm × 1.0 mm
  • EIA 3216-12: 3.2 mm × 1.6 mm × 1.2 mm
  • EIA 3216-18: 3.2 mm × 1.6 mm × 1.8 mm

EIA stands for Electronic Industries Alliance, and is a group that develops standards for the electronics manufacturing industry.

EIA 3216 is a standard footprint for Tantalum capacitors that have a size of 3.2 mm × 1.6 mm × 1.0 mm

Wikipedia has a list of EIA standard footprint
