陶瓷电容器是以陶瓷为介电质的电容器。其结构是由二层或更多层交替出现的陶瓷层和金属层所组成，金属层链接到电容器的电极。陶瓷材料的成份决定了电容器的电气特性及其应用范围，依稳定性可分为以下三类：

陶瓷电容器是电子设备中最常使用的电容，每年的产量约为一兆颗。其中最常用的是积层陶瓷电容器（MLCC），且有采用表面安装技术的组件。

A ceramic capacitor is a fixed value capacitor in which ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications. Ceramic capacitors are divided into two application classes:
