What is a ceramic capacitor, and what are the differences between a ceramic capacitor and an electrolytic capacitor?

Ceramic capacitors are a commonly used electronic component, widely applied in industries such as electronics, telecommunications, and computing. They primarily form the structure of SN65HVD11DR capacitors by embedding metal electrodes within a ceramic substrate. With characteristics like compact size, lightweight, and excellent stability, ceramic capacitors are extensively utilized in various electronic circuits.
