Abstract

The invention provides an SMD safety ceramic capacitor, which relates to a ceramic capacitor with a hollow middle part formed by performing ceramic modification preparation based on a KNN relaxation system, and belongs to the field of electrical elements.A ceramic capacitor in which corrugated inner electrodes performs high-voltage breakdown to improve the overall range and which conducts heat diffusion through a hollow in the middle is provided. The ceramic capacitor comprises terminal electrodes and an MLCC, the terminal electrodes are symmetrically arranged at the ends of the MLCC, multiple layers of inner electrodes are arranged in the MLCC, the inner electrodes are connected with the terminal electrodes, a hollow structure is transversely arranged in the middle of the LLCC, the inner electrodes are of a corrugated structure, the ceramic of the MLCC is prepared by adopting a tape casting process, and the excellent performance of combining a large electrocaloric effect and a wide room temperature refrigeration working temperature area is successfully obtained in a lead-free MLCC device by utilizing the synergistic effect of KNN relaxation phase change and a high electric field.

Description

Technical field

[0001] The present invention provides a patch conventional ceramic capacitor relates to a ceramic capacitor for a central hollowed ceramic capacitor by a ceramic modification by a Knn relaxation system, which is a ceramic capacitor in a central hollow. Background technique

[0002] Multi-layer ceramic capacitor MLCCITOR is laminated by a ceramic medium diaphragm of a printed electrode (internal electrode) in a misalignment, and the ceramic chip is formed by a disposable high temperature sintering, and then two ends of the chip. The upper metal layer (external electrode) thus forming a structure similar to a monolithic, so it is also called a monolithic capacitor. Multi-slice type ceramic capacitor MLCC except for the "compact communication" of the capacitor, it has a small size, large specific, long life, high reliability, suitable for surface mounting. With the development of society, multi-layer slice ceramic capacitors have been widely used in the fields of ele...
