<description>&lt;h3&gt;CAP-PTH-SMALL-KIT&lt;/h3&gt;
Commonly used for small ceramic capacitors. Like our 0.1uF (http://www.sparkfun.com/products/8375) or 22pF caps (http://www.sparkfun.com/products/8571).&lt;br&gt;
&lt;br&gt;
&lt;b&gt;Warning:&lt;/b&gt; This is the KIT version of this package. This package has a smaller diameter top stop mask, which doesn't cover the diameter of the pad. This means only the bottom side of the pads' copper will be exposed. You'll only be able to solder to the bottom side.</description>
