<library name="mb_caps-electro">
<description>&lt;b&gt;Capacitors, Polar Electrolytic, Radial &lt;/b&gt;
&lt;ul&gt;
&lt;li&gt;large value capacitors: .22 - 470uF (uF = µF = mF)
&lt;li&gt;often used in power supply filters
&lt;/ul&gt;</description>
<packages>
<package name="063_025">
<description>&lt;b&gt;6.3mm diameter, 2.5 mm lead spacing, 0.1" pad spacing&lt;/b&gt;</description>

<library name="mb_diodes">
<description>&lt;b&gt;Diodes&lt;/b&gt;
&lt;ul&gt;
&lt;li&gt;Zener 1N47xx (as in protection for the MOSFET in the AMZ MOSFET Booster)
&lt;li&gt;rectifier 1N4001-1N4008 (for polarity reversal protection in power supply sections)
&lt;li&gt;clipping 1N914 (as in a TS808)
&lt;li&gt;LED (light emitting diode, 3mm and 5mm)
&lt;li&gt;mostly gathered from Eagle libraries
&lt;/ul&gt;</description>

<description>&lt;b&gt;Potentiometers&lt;/b&gt;
&lt;ul&gt;
&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;</description>

&lt;p&gt;potentiometer for showing off-board connections</description>

<description>&lt;b&gt;Supply&lt;/b&gt;
&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;</description>

&lt;li&gt;6mm long -- the size of 1/4 watt resistors
&lt;li&gt; all resistor values have the same size package; you choose the value of resistance

<description>&lt;b&gt;RESISTOR&lt;/b&gt;&lt;br&gt;
&lt;br&gt;
length: 6mm&lt;br&gt;

spacing: 3 holes

&lt;p&gt;This length resistor applies to 1/4 watt metal film.</description>
</package>
</packages>
</library>
<library name="mb_caps-box">
<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>
<packages>
