Ceramic capacitors are usually physically and capacitance-wise small. You are unlikely to find a ceramic capacitor larger than 10 microfarads (μF). A surface-mount ceramic cap is commonly found in packages like 0402 (0.4mm x 0.2mm), 0603 (0.6mm x 0.3mm), or 0805.
A capacitor is a passive two terminal electrical component used to store energy electrostatically in an electric field. A ceramic capacitor is a type of fixed value capacitor where the ceramic material acts as the dielectric.
Ceramic disc capacitors are a type of capacitor that are used across brush DC motors to minimize RF noise. They are smaller capacitors compared to electrolytic caps, and offer lower ESR and leakage currents, making them a more near-ideal capacitor. Ceramics are usually the least expensive option.
