Ceramic capacitors are a type of passive electronic component known as a capacitor, specifically utilizing ceramic materials in its construction. They are widely used in various applications due to their reliability, compact size, and relatively low cost compared to other types of capacitors. These capacitors are often employed in circuits where a stable DC voltage is required or to filter out high-frequency noise. Their primary function is to store electrical energy within the ceramic material itself, which acts as both the dielectric (insulating) layer and the capacitor's housing.
