High-temperature ceramic plate type array capacitor and preparation method thereof

Abstract

The invention discloses a high-temperature ceramic plate type array capacitor and a preparation method thereof. The capacitor main body includes: a ceramic medium, an inner electrode and a terminal electrode, the capacitor main body is of a multilayer plate-shaped structure with a plurality of signal holes, the inner electrode comprises a plurality of common grounding electrodes and a plurality ofsignal electrodes, the plurality of common grounding electrodes and the plurality of signal electrodes are alternately arranged in the lamination direction of the ceramic medium, and the projectionsof the common grounding electrodes and the signal electrodes on a lamination plane are partially overlapped; each common grounding electrode extends inwards from the outer edge of the ceramic medium and is spaced from the signal hole; and each signal electrode extends outwards from the signal hole and is spaced from the outer edge of the capacitor and the signal electrode of the adjacent signal hole. The problems that in the prior art, a discrete ceramic tube type capacitor filter is poor in mechanical shock resistance and prone to damage, and the reliability of the whole filter is prone to being reduced are solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of capacitors, in particular to a high-temperature ceramic plate array capacitor and a preparation method thereof. Background technique [0002] With the development of electronic equipment towards high frequency, high speed, high sensitivity, high reliability, multi-function, miniaturization and informatization, electrical connectors also develop towards miniaturization, high density, high frequency and multi-function. The need for equipment to combat electromagnetic interference is growing rapidly. There are two main ways to resist electromagnetic interference: shielding and filtering. Most traditional filter connectors use tube capacitors for filtering. Tubular capacitors are characterized by large size, low capacitance, poor mechanical strength, and low reliability. Since the tubular capacitor is a single-layer ceramic structure, the thickness of the ceramic tube is generally...
