5 results about "Ceramic capacitor" patented technology

New designs for multilayer ceramic capacitors are described with high voltage capability without the need of coating the part to resist surface arc-over. One design combines a high overlap area for higher capacitance whilst retaining a high voltage capability. A variation of this design has increased voltage capability over this design as well as another described in the prior art although overlap area and subsequently capacitance is lowered in this case. These designs are compared to the prior art in examples below.

A composite electronic component includes a composite body in which a multilayer ceramic capacitor and a ceramic chip are coupled to each other, the multilayer ceramic capacitor including a first ceramic body in which a plurality of dielectric layers and internal electrodes disposed to face each other with respective dielectric layers interposed therebetween are stacked, and first and second external electrodes disposed on both end portions of the first ceramic body, and the ceramic chip being disposed on a lower portion of the multilayer ceramic capacitor and formed of a ceramic material having substantially no piezoelectric property, wherein a ratio (T/L) of thickness (T) of the ceramic chip to length (L) of the multilayer ceramic capacitor is selected to minimize vibration of the ceramic chip.

The invention discloses a method for detecting dispersibility of electrocondution slurry for MLCC (Multi-layer Ceramic Capacitors). The method comprises the steps of: smearing electrocondution slurryto be detected on a smooth plastic film by employing a film scraper to obtain a sample film with a uniform surface and uniform thickness; putting the sample film and the plastic film into the center of an oven for drying; taking out the dried sample film and the plastic film from the oven; taking off the plastic film on the dried sample film on clean paper, keeping the integrity of the dried sample film, and cutting the sample film into a plurality of sample films to be tested with the same lengths and the same width by employing a cutter; measuring each sample film to be detected by an MD-300S electric specific gravity balance to obtain the density of the dried film corresponding to each sample to be detected, wherein the density of the dried film corresponding to the electrocondution slurry to be detected is the average value of the measurement results. The method provided by the invention can determine the dispersibility of the electrocondution slurry according to the density of thedried film, can assess the dispersibility of the electrocondution slurry in the submicron order, and is rapid and convenient.

A multilayer ceramic capacitor includes a laminate including a plurality of dielectric layers laminated one on the other, the laminate being in a cuboid or substantially cuboid shape. The multilayer ceramic capacitor includes external electrodes on the end surfaces of the laminate. A first inner electrode layer exposed through the first end surface and a second inner electrode layer exposed through the second end surface are provided on the dielectric layer. A first region and a second region are defined in the first inner electrode layer and the second inner electrode layer, in which coverages of the first inner electrode layer and the second inner electrode layer to the dielectric layer are greater in the first region than in the second region.
