硬件电路设计之“原理图标号”

<p>本文主要介绍原理图设计中常见的器件标识，包括阻容感、接插件、晶振、芯片等等。实际应用中可根据实际情况进行分类，这样导出BOM的时候会非常方便。</p>

<p><strong>1、电阻类</strong></p>

<p>---------------------------------------------------</p>

<p>&lt;Reference&gt;&lt;Resistor&gt;</p>

<p>---------------------------------------------------</p>

<p>R&nbsp; &nbsp; &nbsp; : Resistor</p>

<p>RP&nbsp; &nbsp; : Resistor Packs</p>

<p>RT&nbsp; &nbsp; : Resistor Thermistors</p>

<p>RV&nbsp; &nbsp; : Resistor Varistor</p>

<p>VR&nbsp; &nbsp; : Variable Resistor</p>

<p>原理图中电阻的标识信息可以参考下图（包括阻值、精度、功率（和封装相关）），这样可以方便的导出BOM，同时可以很直观的去看待放置的电阻是否合适。</p>
