&lt;li&gt;chassis-mount (e.g., Alpha 16mm) pots&lt;/li&gt;
&lt;li&gt;board-mount trim pots (1/4" and 3/8")&lt;/li&gt;
&lt;li&gt; all pot values have the same size package; you choose the value of resistance

&lt;ul&gt;
&lt;li&gt;input, output, ground, and power supply.  
&lt;li&gt;these are used on a schematic for placeholders and on a board for pads for off-board components like jacks.

&lt;ul&gt;
&lt;li&gt;1000pF - 2.2uF  (uF = µF = mF)
&lt;li&gt;popular nonpolarized capacitors because they are small
&lt;li&gt;these have short leads so that pad spacing equals lead spacing
&lt;li&gt;e.g., WIMA capacitors
