Abstract

The invention discloses a high-frequency low-impedance electrolytic capacitor, which comprises an outer shell. The outer shell adopts a hollow cylinder structure; a core package is mounted in an innercavity of the outer shell; the outer shell is opened; an insulating cover plate is mounted at the opening in the upper end of the outer shell; a layer of protective film covers the inner side of theinsulating cover plate; two through holes are formed in the insulating cover plate; and a positive pin and a negative pin are inserted to the two through holes respectively, and the positive pin and the negative pin are electrically connected with the positive end and the negative end of the core package. The structure design is novel, the manufacturing is convenient, the manufacturing cost is low, the loss is low, the high-frequency characteristic is good, high temperature resistance, heat resistance and corrosion resistance properties are achieved, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of electrolytic capacitors, in particular to a high-frequency low-impedance electrolytic capacitor. Background technique [0002] An electrolytic capacitor is a capacitor formed by anodizing a thin layer of oxide on the surface of valve metals such as aluminum, tantalum, niobium, and titanium as a dielectric, and using the electrolyte as a cathode. The anode of electrolytic capacitors usually adopts the structure of corroded foil or powder sintered block. Its main feature is that it has a high capacity per unit area, and it has incomparable advantages over other types of capacitors in terms of small size and large capacity. At present, the electrolytic capacitors produced industrially are mainly aluminum electrolytic capacitors and tantalum electrolytic capacitors. The existing electrolytic capacitors have poor high-frequency characteristics, poor corrosion resistance, easy damage, and short service life. T...
