<library name="rc-master-smd">
<description>&lt;b&gt;R/C MASTER-SMD! - v1.14 (03/30/2013)&lt;/b&gt;&lt;p&gt;
&lt;p&gt;This library is a collection of SMD ONLY resistors and capacitors by various manufacturers. The pad sizes, spacing and silkscreen widths have been tweaked for use in dense fine pitch layouts where space, alignment and precision are critical. In general these components are designed for routing in grid increments of 5 mils&lt;/p&gt;
&lt;p&gt;* Silkscreen line elements are a minimum of 8 mils in width. All components have text sizes of 0.032"  or 0.04".&lt;/p&gt;
&lt;p&gt;* A silkscreen text values use a ratio of 18 in all cases.&lt;/p&gt;
&lt;p&gt;* ALL PADS AND PART OUTLINES ARE SNAPPED TO A 5 MIL GRID!&lt;/p&gt;
&lt;p&gt;* See ULP script &lt;b&gt;migrate-rc-master.ulp&lt;/b&gt; to auto-migrate parts from &lt;b&gt;rcl.lbr&lt;/b&gt;&lt;/h4&gt;.&lt;/p&gt;
&lt;p&gt;&lt;h4&gt;All components are prefixed using the following conventions:&lt;/h4&gt;&lt;/p&gt;&lt;br&gt;
&lt;table width="380" border="1" bordercolor="#000000"&gt;
  &lt;tr&gt; 
    &lt;td width="81" bgcolor="#33CCFF"&gt;&lt;div align="center"&gt;&lt;strong&gt;Prefix&lt;/strong&gt;&lt;/div&gt;&lt;/td&gt;
    &lt;td width="289" bgcolor="#33CCFF"&gt;&lt;div align="center"&gt;&lt;strong&gt;Description&lt;/strong&gt;&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt; 
    &lt;td&gt;&lt;div align="center"&gt;CBP_&lt;/div&gt;&lt;/td&gt;
    &lt;td&gt;&lt;div align="center"&gt;Bipolar Electrolytic Types&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt; 
    &lt;td&gt;&lt;div align="center"&gt;CCA_&lt;/div&gt;&lt;/td&gt;
    &lt;td&gt;&lt;div align="center"&gt;Chip Cap Array Types&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt; 
    &lt;td&gt;&lt;div align="center"&gt;CP_&lt;/div&gt;&lt;/td&gt;
    &lt;td&gt;&lt;div align="center"&gt;Polarized Electrolytic/Tantalum Types&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt; 
    &lt;td&gt;&lt;div align="center"&gt;C_&lt;/div&gt;&lt;/td&gt;
    &lt;td&gt;&lt;div align="center"&gt;Non-Polarized Film / Chip Types&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt; 
    &lt;td&gt;&lt;div align="center"&gt;FB_&lt;/div&gt;&lt;/td&gt;
    &lt;td&gt;&lt;div align="center"&gt;Simple Ferrite Bead Types&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt; 
    &lt;td&gt;&lt;div align="center"&gt;L_&lt;/div&gt;&lt;/td&gt;
    &lt;td&gt;&lt;div align="center"&gt;Simple Chip Inductors&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt; 
    &lt;td&gt;&lt;div align="center"&gt;R_&lt;/div&gt;&lt;/td&gt;
    &lt;td&gt;&lt;div align="center"&gt;Resistor Types&lt;/div&gt;&lt;/td&gt;
  &lt;/tr&gt;
&lt;/table&gt;
&lt;p&gt;
As a general guideline, SMD resistors are typically rated as follows:&lt;p&gt;
0402 = 1/16 watt&lt;br&gt;
0603 = 1/10 watt&lt;br&gt;
0805 = 1/8  watt&lt;br&gt;
1206 = 1/4  watt&lt;br&gt;
2010 = 1/2  watt&lt;br&gt;
2512 = 1    watt&lt;br&gt;&lt;p&gt;
