&lt;ul&gt;
&lt;li&gt;large value capacitors: .22 - 470uF (uF = µF = mF)
&lt;li&gt;often used in power supply filters

<description>&lt;b&gt;Capacitors, Film, Box&lt;/b&gt;
&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
&lt;/ul&gt;</description>
