Ceramic capacitors are made by coating two sides of a small ceramic disc with a metal film (such as silver) and then stacking them together in the capacitor packaging. A single ceramic disc of about 3-6 mm can be used to reach very low capacitance. The dielectric constant (Dk) of ceramic capacitor dielectrics is very high, so …

Multilayer ceramic capacitors (MLCCs) have broad applications in electrical and electronic systems owing to their ultrahigh power density (ultrafast charge/discharge rate) and excellent stability (1–3).However, the generally low energy density U e and/or low efficiency η have limited their applications and further development …
