Multilayer ceramic capacitors

Significant advances have been achieved in the manufacturing technology of high volumetric multilayer ceramic capacitors (MLCs) comprised of hundreds of dielectric layers less than 3 μm in thickness. A capacitor consists of a BaTiO3-based X7R ceramic and nickel internal electrodes. The effects of acceptor and donor dopants on reliability have been studied extensively, and a reliable 10 μF MLC has been achieved with an EIA 1206 size (3.2 × 1.6 × 1.5 mm), which is capable of replacing tantalum electrolytic capacitors.
