电容器的介绍
电容器,通常简称其容纳电荷的本领为电容,用字母C表示。定义1:电容器,顾名思义,是“装电的容器”,是一种容纳电荷的器件。英文名称:capacitor。电容器是电子设备中大量使用的电子元件之一,广泛应用于电路中的隔直通交,耦合,旁路,滤波,调谐回路, 能量转换,控制等方面。定义2:电容器,任何两个彼此绝缘且相隔很近的导体(包括导线)间都构成一个电容器。
电容与电容器不同。电容为基本物理量,符号C,单位为F(法拉)。
通用公式C=Q/U平行板电容器专用公式:板间电场强度E=U/d ,电容器电容决定式 C=εS/4πkd
随着电子信息技术的日新月异,数码电子产品的更新换代速度越来越快,以平板电视(LCD和PDP)、笔记本电脑、数码相机等产品为主的消费类电子产品产销量持续增长,带动了电容器产业增长。
电容器是由两个电极及其间的介质材料构成的。介质材料是一种电介质,当被置于两块带有等量异性电荷的平行极板间的电场中时,由于极化而在介质表面产生极化电荷,遂使束缚在极板上的电荷相应增加,维持极板间的电位差不变。这就是电容器具有电容特征的原因。电容器中储存的电量Q等于电容量C与电极间的电位差U 的乘积。电容量与极板面积和介电材料的介电常数 ε成正比,与介电材料厚度(即极板间的距离)成反比。
