Problems solved by technology
Therefore, if the cross-section inspection of multilayer ceramic capacitors or ceramic bodies with similar width and thickness dimensions is to be carried out, when the chips to be inspected are arranged in the mold, there is a possibility that the chips may be misaligned, that is, as many as half of the chips may be due to orientation orientation. Failure to obtain the desired grinding surface, i.e. viewing surface, by mistake, resulting in reduced inspection efficiency and operational difficulties

The invention discloses a multilayer ceramic capacitor, which comprises a ceramic body and a first external electrode and a second external electrode respectively arranged at two opposite ends of the ceramic body; and a second part; the first part includes a plurality of first internal electrode layers and a plurality of second internal electrode layers alternately stacked; the second part includes a plurality of third internal electrode layers and a plurality of fourth internal electrode layers alternately stacked An internal electrode layer; the content of nickel in the first part is greater than the content of nickel in the second part. When this multilayer ceramic capacitor or ceramic body is carried out cross-section inspection, can carry the sample to be inspected with flat plate and make the sample to be inspected on the flat plate be turned over with the permanent magnet placed under the flat plate, because the first part of the ceramic body of above-mentioned multilayer ceramic capacitor The nickel content in the second part is more than that in the second part, and the sample to be tested is easily turned over to a uniform orientation.
Description
technical field [0001] The invention relates to the field of electronic components, in particular to a multilayer ceramic capacitor. Background technique [0002] A conventional multilayer ceramic capacitor includes a cuboid ceramic body and two external electrodes disposed at opposite ends of the ceramic body. The ceramic body includes a plurality of internal electrode layers alternately stacked and respectively connected to external electrodes of different polarities and a plurality of dielectric layers respectively stacked between the internal electrode layers of different polarities, so that a multilayer ceramic capacitor can obtain a higher High capacity value. With the development of multilayer ceramic capacitors to high capacity, the number of stacked layers of dielectric layers and internal electrode layers increases, so that the height of multilayer ceramic capacitors increases and is equal to or close to its width. Therefore, if the cross-section inspection of mu...
