Ceramic capacitors are a type of capacitor that utilize ceramic materials to store electrical energy, characterized by their compact size and relatively low cost. They are often used in electronic circuits due to their ability to filter out noise and regulate voltage. Note: Ceramic capacitors can be further divided into two main categories: Class 1 (high-quality) and Class 2 (more general-purpose). The choice of which type to use depends on the specific requirements of a project or application.
