Book Abstract

第2章电子元件基础
识别和检测电子元件是从事计算机硬件维修的一项基本功，准确识别和检测电子元件是否正常，对于电子线路的维修有重要意义。不同的电子元件，检测方法有所不同，本章主要介绍电阻器、电容器、电感器、半导体器件等电子元件的识别、检测方法与检测技巧。
2.1 电阻器
在电子线路中，具有电阻性能的实体组件称为电阻器，习惯上简称电阻。电阻器的主要功能是调节电路中的电流或电压。电阻器一般分固定电阻器、可变电阻器和敏感电阻器三大类。通常把可变电阻器叫做电位器。
2.1.1 电阻器的分类
电阻器的品种繁多，可按材料与用途进行分类。
1.按材料分类
电阻器按材料可分为合金型、薄膜型和合成型三种。
（1）合金型
用块状电阻合金拉制成合金线或碾压成合金箔，制成电阻，如线绕电阻、精密合金箔电阻等。
（2）薄膜型
在玻璃或陶瓷基体上沉积一层电阻薄膜，膜厚一般在几微米以下，有碳膜、金属膜、化学沉积膜及金属氧化膜等薄膜。
（3）合成型
电阻体本身由导电颗粒和有机（或无机）黏接剂混合而成，可制成薄膜或实心两种，常见的有合成膜电阻和实心电阻。
2.按用途分类
电阻器按用途可分为通用型、精密型、高频型、高压型、高阻型和集成电阻等几种。
