Abstract

A ceramic capacitor for reducing parasitic inductance belongs to the technical field of ceramic capacitors and comprises a first chip, ceramic dielectric thin pieces, a second chip, two grounding external electrode plates and two signal external electrode plates, wherein the first chip comprises a first ceramic substrate and a first inner electrode, the first inner electrode horizontally extends to a left side surface and a right side surface of the first ceramic substrate, the second chip comprises a second ceramic substrate and a second inner electrode, the second inner electrode longitudinally extends to a front side surface and a rear side surface of the second ceramic substrate, the ceramic dielectric thin pieces are sandwiched between the first chip and the second chip and are laminated to form a chip body, the ceramic dielectric thin piece is arranged at each of an upper side and lower side of the chip body, the two grounding external electrode plates are respectively arranged at a front side surface and a rear side surface of the second chip, and the two signal external electrode plates are respectively arranged at a left side surface and a right side surface of the first chip. The ceramic capacitor is used for solving the technical problem that a large amount of parasitic inductance exists in the ceramic capacitor.

Description

Technical field [0001] The invention relates to the technical field of ceramic capacitors, in particular to a ceramic capacitor that reduces parasitic inductance. Background technique [0002] At present, most of the chip multilayer ceramic capacitors used have a two-terminal electrode structure. The structure is that the internal electrodes on the chip sandwich the ceramic dielectric and are alternately stacked in a staggered manner. After high temperature sintering, the two Seal the outer electrode on the end. This kind of ceramic capacitor has a unidirectional transmission due to its internal transmission and a long transmission path, which still has a large amount of parasitic inductance. The existence of parasitic inductance will cause the performance of the ceramic capacitor to decrease. Summary of the invention [0003] The purpose of the present invention is to provide a ceramic capacitor with reduced parasitic inductance, which is used to solve the technical problem of a...
