Ceramic capacitors are also called porcelain dielectric capacitors or monolithic capacitors. As the name implies, porcelain dielectric capacitors are capacitors whose dielectric material is ceramic. The classification of ceramic capacitors is mainly based on the following materials: According to different ceramic materials, it can be divided into two types: low-frequency ceramic capacitors and high-frequency ceramic capacitors. [...]
