Problems solved by technology

[0003] However, due to the difficulties in the advancement of several major industries in the technical field, capacitors with low loss angle and high power factor Q value are a difficult point that everyone has been paying attention to but difficult to solve. If it can be solved well or to a large extent If the power factor Q value can be increased, it will be favored by the mobile phone wireless charging adapter market. Therefore, the present invention proposes a new high-Q value capacitor to solve the above problems

Abstract

The invention provides a novel high-Q-value capacitor, and relates to the field of capacitors. The novel high-Q-value capacitor comprises a capacitor core, a capacitor shell and tinned copper wires, wherein an insulating layer polypropylene film is arranged in the capacitor core. According to the novel high-Q-value capacitor, by changing a conventional method that the polypropylene film of the capacitor adopts traditional high-oil shielding and aluminum-zinc high-square-resistance evaporation, a small amount of special oil is added as a shielding layer in the evaporation process to prevent thepollution of a frequency band, and the phenomena of high-frequency loss and Q value reduction caused by the pollution of the frequency band due to large oil amount are avoided; meanwhile, a thin layer of aluminum is evaporated to serve as an electrode, so that the self-repair effect is achieved; the higher the Q value is, the lower the loss value of the capacitor is, the higher the efficiency is,so that double designs of low-oil shielding and pure-aluminum low-square resistance in the evaporation process are adopted to ensure a characteristic that the capacitor can realize high Q value and low loss; and the novel high-Q-value capacitor is easy to machine, relatively low in cost and relatively high in power factor, and meets the urgent needs of current wireless charging.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a novel high-Q capacitor. Background technique [0002] With the increasingly fierce competition in the domestic capacitor market, major capacitor manufacturers have started a new revolution in the technology-led development of the capacitor industry. In addition, the overall performance of the world's capacitor industry is mature, and the core technology of capacitors is mostly in the hands of foreign capacitor giants, so it has also caused domestic manufacturers to shift their work focus to new strategies and new fronts in the technical field. [0003] However, due to the difficulties in the advancement of several major industries in the technical field, capacitors with low loss angle and high power factor Q value are a difficult point that everyone has been paying attention to but difficult to solve. If it can be solved well or to a large extent If the Q value of the power factor ca...
