    贴片电感

    贴片电感是什么?

    贴片电感,又称SMD电感器,是一种贴装在印刷电路板表面、而不是通过传统的通孔技术安装的电感器。

    贴片电感的工作原理

    • 贴片电感是一种使用电磁场控制电流的无源元件(即需要外部电源)。
    • 贴片电感可焊接到印刷电路板上的焊盘,从而形成电路。

    贴片电感的应用

    • 贴片电感可用于电源电路中,以控制电压或电流。
    • 贴片电感常用于防止电压或电流变化传递到电路中的其他元件中,避免元件损坏。
    • 贴片电感可用于高频率运行设备,如移动通信系统、手机、蓝牙设备和调谐器。

    贴片电感的类型

    贴片电感有多种类型,即绕线式、叠层式、编织式和薄膜片式电感器。常用的是绕线式和叠层式两种类型。

    • 绕线式贴片电感的磁芯由铁等磁性金属制成,周围缠绕有电线。当电流流经线圈电线时,能量储存在磁场中,而线圈电线具有厚绝缘层,使电感器适用于大电流。
    • 叠层式贴片电感在上部有两个导电线圈。这些线圈连接至下层的两个类似线圈,这两个线圈同样在电流流经时将能量储存在磁场中。
