The invention discloses an adjustable laminated ceramic capacitor, and the capacitor comprises a ceramic substrate and a sliding block. The interior of the ceramic substrate comprises one upper electrode and more than two lower electrodes. A sliding groove is formed at one side of the ceramic substrate body. A leading-out end of the lower electrode is located on the inner wall of the sliding groove, and a leading-out end of the upper electrode is located on the side, not provided with the groove, of the ceramic base body. The ceramic substrate outside the leading-out ends of the upper and lower electrodes are provided with metal sealing end plating layers. A sliding block sliding in cooperation with the sliding groove is arranged in the sliding groove. A first metal contact in contact withthe leading-out end of the lower electrode and a second metal contact in contact with the metal sealing end coating are arranged on the sliding block. The upper electrode serves as an electrode platefor fixing an adjustable capacitor, and different lower electrodes are selected to serve as another electrode plate of the adjustable capacitor through movement of the sliding block, so that adjustment of the capacitor in the ceramic substrate is achieved. According to the invention, multi-capacitance adjustment of the monolithic laminated ceramic capacitor is realized by using a simple structure, and a larger design space is provided for miniaturization and high-density integration of an electronic system.
Description
technical field [0001] The invention relates to the field of electronic components, in particular to an adjustable laminated ceramic capacitor suitable for thick film technology. Background technique [0002] As early as the beginning of this century, the annual output of discrete components in the world has reached 700-900 billion pieces. In order to adapt to traditional integration technologies such as surface mount, the chip rate of discrete components exceeds 80% in many developed countries. As an important discrete passive component, chip ceramic capacitors are currently mass-produced using thick-film technology. Their common structure is formed by alternating overlapping internal electrodes and dielectric layers. Different types of internal electrodes are led out from both sides to seal . Such as figure 1 Shown is the cross-sectional structure of a common multilayer ceramic capacitor, where 1 is the internal electrode drawn from the left, 2 is the internal electrode ...
