20130038979 | MULTILAYER CAPACITOR - A multilayer capacitor that can suppress electrostrictive vibration without material constraint and with applicability to various structures, including general-purpose structures. A multilayer capacitor has: an element body formed of dielectric ceramic; and a plurality of internal electrodes disposed inside the element body such that the internal electrodes are stacked with ceramic layers sandwiched therebetween. The multilayer capacitor is provided with a capacitor area which includes the plurality of internal electrodes and a first suppression area and a second suppression area for reducing electrostriction caused by the plurality of internal electrodes so as to suppress noise. The first suppression area is adjacent to the capacitor area and the thickness of the second suppression area is determined according to the arrangement of the plurality of internal electrodes. | 02-14-2013 |
20130083484 | COMPOSITE ELECTRONIC COMPONENT AND STRUCTURE FOR MOUNTING COMPOSITE ELECTRONIC COMPONENT - A composite electronic component includes electronic components, a conductor layer, and a support. Each of the electronic components includes a first terminal electrode and a second terminal electrode that are arranged on respective opposing surfaces of an element body. The conductor layer electrically connects the first terminal electrodes of the electronic components to one another. The conductor layer is arranged on the support. The second terminal electrodes of the electronic components function as mounting terminal electrodes to be connected to terminals of a circuit substrate. | 04-04-2013 |
