20120119867 | MULTILAYER COIL COMPONENT - A multilayer coil component is provided to have high reliability and in which internal stress arising from the difference in firing shrinkage behavior and/or thermal expansion coefficient between ferrite layers and internal conductor layers is alleviated without forming conventional voids between the ferrite layers and the internal conductor layers. A method of manufacturing a multilayer coil includes a step of isolating interfaces between internal conductors and surrounding ferrite by allowing a complexing agent solution to reach interfaces between the internal conductors and the surrounding ferrite through side gap portions from side surfaces of a ferrite element including a helical coil. The complexing agent solution contains at least one selected from the group consisting of an aminocarboxylic acid, a salt of the aminocarboxylic acid, an oxycarboxylic acid, a salt of the oxycarboxylic acid, an amine, phosphoric acid, a salt of phosphoric acid, and a lactone compound. | 05-17-2012 |
20130088316 | ELECTRONIC COMPONENT AND MANUFACTURING METHOD THEREOF - An electronic component that can be prevented from being mounted on a circuit board with inclination, and a manufacturing method thereof are provided. An electronic component is mountable on a circuit board including a first land and a second land. The electronic component includes outer electrodes on a lower surface of a stack to be arranged along a direction and are connectable to the first land and the second land, respectively. With the eletronic component mounted to the circuit board, respective contact surfaces of the outer electrodes to the first land and the second land have a structure being symmetric about a line parallel to the direction, and each respective contact surface is divided into a plurality of portions. | 04-11-2013 |
20130093558 | ELECTRONIC COMPONENT - An electronic component that can be prevented from being shifted from a normal mount position and can be manufactured with a low cost is provided. The component is configured by stacking a plurality of insulating layers and a plurality of inner conductors provided on the respective insulating layers. The connection conductors have respective exposure portions that are each exposed between corresponding ones of the insulating layers at a surface of the stack. An outer electrode is formed, for example, by plating on the lower surface so that the exposure portions are covered with the outer electrode. The plurality of exposure portions do not have uniform thicknesses or are not arranged at uniform intervals in the stacking direction. | 04-18-2013 |

20140313792 | POWER DELIVERY DEVICE, AC ADAPTER, AND ELECTRONIC APPARATUS - The PD device comprises a primary-side controller configured to control an input current of a DC/DC converter disposed between an input and an output, and a secondary-side controller connected with AC coupling to the output, and configured to feedback electric power information of the output to the primary-side controller. The primary-side controller varies an output voltage value and an available output current capacity of the DC/DC converter by controlling the input current on the basis of the electric power information fed back from the secondary-side controller. The primary-side controller can change an overpower detecting set value in accordance with the target equipments connected to the output, thereby executing the power change of the DC/DC converter. | 10-23-2014 |
