Ceramic Capacitor

A ceramic capacitor generally consists of a sintered body in the form of a chip, and a pair of external electrodes formed on both terminals of the chip.  In a multi-layer ceramic capacitor, the sintered body is generally made of alternately laminated dielectric layers and internal electrodes. The adjacent two internal electrodes are aligned with one dielectric layer sand witched there between and are each electrically connected to the external electrodes. Generally, a multilayer ceramic capacitor (multilayer chip capacitors) comprises dielectric ceramic layers, internal electrodes disposed between the dielectric ceramic layers, and an external electrode connected to these internal electrodes on both sides of the dielectric ceramic layers. Monolithic ceramic capacitors have a rectangular shape, and are provided with external electrodes at the opposite ends. Ceramic dielectric layers are each placed between the internal conductors. A semiconductive ceramic capacitor used as a passive electronic circuit element is generally classified into a surface-layer type ceramic capacitor and a boundary-layer ceramic capacitor. The surface-layer semiconductive ceramic capacitor includes a reduction and reoxidation type semiconductive ceramic capacitor and a barrier-layer type semiconductive ceramic capacitor.
