Abstract

The invention relates to a cyclic ceramic dielectric capacitor, which comprises two sets internal electrodes. Every set internal electrode is connected with a terminal electrode and comprises one or more layers conductive films, between the adjacent conductive films that belong to different internal electrodes is ceramic dielectric membrane lay that alternately lap on the internal electrode conductive film; the dielectric membrane and protective layer are laminated into homogeneous capacitor and both present as circularity, conductive films of the two sets internal electrodes are cyclic and the capacitor is cylinder with holes; the terminal electrode comprises outer-ring and inner-ring ones, wherein the metallized films of the inner-ring and outer-ring terminal electrode separately cover on the inner wall of the through-hole and the outer wall of the cylinder.

Description

【Technical field】 [0001] The present invention relates to a capacitor, and more specifically, the present invention relates to a ring-shaped high-frequency filter capacitor and a preparation method thereof. 【Background technique】 [0002] In recent years, along with the digitalization of information processing equipment and communication equipment, and the speeding up of information processing capability, the digital signals processed by these equipments are obviously rapidly increasing in frequency. Therefore, the noise generated in these devices tends to develop further into the high-frequency band. On the other hand, with the high voltage, miniaturization and high power of these devices, the elimination of high-power high-frequency interference clutter has been quickly listed as a subject of technical transformation in related fields. [0003] In order to eliminate high-frequency noise, electronic components that can prevent electromagnetic wave interference or suppress ...
