关于 固定电感器
电感器，也称为线圈、扼流圈或反应器，是基本的被动电子元件，具有两个端口，当电流通过它们流动时，会在磁场中储存能量。当电流变化时，磁场会在导体中产生感应电压。感应电压具有与生成它的电流变化相反的极性，从而产生自感效应。
电感的测量单位是亨利（H），以美国物理学家约瑟夫·亨利命名。电感器存在于各种形式和尺寸中，范围从微亨到毫亨甚至更高。
在实际应用中，电感器可用于滤除不需要的高频信号，并在DC-DC转换器中存储和释放能量。电感器还可与电容器结合使用，创建滤波特定频率的谐振电路。
电感器有不同的安装选项，包括表面贴装技术（SMT）、通孔和机箱安装。表面贴装电感器适用于紧凑设计，而通孔电感器提供了稳健性和易于组装性。机箱安装电感器适用于工业和重型应用的更加坚固的设计。
总之，电感器是电子电路中不可或缺的组件，提供能量存储、信号滤波和频率选择功能。这些基本被动元件具有广泛的安装选项和应用，对现代电子学发挥着至关重要的作用。
