Abstract

The invention discloses a chip capacitor, comprising a plurality of circular ring shaped capacitor plates, which are spaced vertically and oppositely to constitute a capacitor plate of the chip capacitor; an inner electrode, which is a metal cylinder, and is inserted into a circular hole in the central portion of each circular ring shaped capacitor plate, cooperatively in fixed contact with the circular holes of some of the circular ring shaped capacitor plates and used for providing a power supply for the circular ring shaped capacitor plates being in contact therewith; an outer electrode, which is a metal drum at the same height as the metal cylinder and with an inner diameter larger than that of the metal cylinder, and is disposed at outer edges of the plurality of circular ring shaped capacitor plates, cooperatively in fixed contact with the outer edges of some of the circular ring shaped capacitor plates, and used for providing a power supply for the circular ring shaped capacitor plates being in contact therewith; and a dielectric used as a dielectric layer. The invention can be used for making a chip capacitor having a relatively high capacitance value on a very small circuit board.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a chip capacitor and a mobile terminal provided with the chip capacitor. Background technique [0002] At present, in recent years, along with the miniaturization of electronic equipment such as mobile phones, personal computers, digital cameras, and digital audio equipment, the demand for further miniaturization and higher capacity of multilayer ceramic capacitors mounted in electronic equipment has gradually increased. As an effective method for realizing a high capacity without increasing the size of the multilayer ceramic capacitor, a method of increasing the facing area of ​​the internal electrodes is mentioned. [0003] In the prior art, large capacitors are often used in circuit design. According to the formula of plate capacitance, the capacitance value is proportional to the effective area, so the volume of large capacitors is generally relatively large, and the area occupied ...
