原理图中元件值标注规则

注：元件值（Component Value）就是元件最主要的特征对应的值。

Component value. Most analog components have a value that must be specified by this field (e.g., 2.7 kΩ). Additional distinguishing information may appear in a “rating” or “tolerance” field (e.g., 1/4 W, 1%). Digital components may give a speed rating here (e.g., -10 for a 10-ns PLD).
