  • Patent number: 9691547
    Abstract: A multilayer ceramic capacitor includes an element body, a first terminal electrode, a second terminal electrode, a plurality of first internal electrode groups, and a plurality of second internal electrode groups. The plurality of first internal electrode groups each include a first number of first internal electrodes connected to the first terminal electrode and arranged in the first direction inside the element body. The plurality of second internal electrode groups each include a second number of second internal electrodes connected to the second terminal electrode and arranged in the first direction inside the element body. The first internal electrode groups and the second internal electrode groups are arranged alternately in the first direction. One of first internal electrodes included in each of the first internal electrode groups and one of second internal electrodes included in each of the second internal electrode groups are opposed to each other.
    Type: Grant

  • Publication number: 20160163455
    Abstract: A multilayer ceramic capacitor includes an element body, a first terminal electrode, a second terminal electrode, and a plurality of internal electrodes. The plurality of internal electrodes include a plurality of first internal electrodes, a plurality of second internal electrodes, a plurality of third internal electrodes, and a plurality of fourth internal electrodes. The element body includes a plurality of first and second regions. The first regions are located between the first internal electrodes opposed with each other. The second regions are located between the first internal electrodes opposed to each other through the third internal electrodes, and between the second internal electrodes opposed to each other through the fourth internal electrodes. The first regions and the second regions are alternately located in the first direction.

  • Patent number: 8228662
    Abstract: In a feedthrough capacitor, a signal internal electrode layer is so arranged that an opposed portion opposed to a ground internal electrode layer is provided with a projection projecting toward a ground electrode, when viewed from a direction of a stack of dielectric layers. Therefore, if a gap amount G is abnormal between an end face with the ground electrode thereon and the signal internal electrode layer, the projection comes in contact with the ground electrode and a short circuit occurs between the ground electrode and terminal electrodes. This feedthrough capacitor thus permits easy detection of abnormality of the gap amount G, based on the presence/absence of a short-circuit failure.
