Embodiment Construction

[0009] exist figure 1 In the embodiment, we further illustrate the present invention by implementing a kind of planar electrolytic capacitor as example:

[0010] exist figure 1 Among them, the shell 1 is made of insulating materials, and plastic shells can also be used. The plastic is required to be thinner on the upper and lower sides; the anode 2, electrolyte 3, and cathode 4 are made of the materials required by ordinary electrolytic capacitors. The difference is that the anode 2 , Electrolyte 3, and cathode 4 can be stacked according to the thickness of the electrolytic capacitor, but not wound, so that the thickness meets the requirements, such as a thickness of 2 mm. According to the thickness of the material, 2-3 layers can be stacked, and the number of stacks needs to be Determine according to the capacity required by the capacitor, the allowable occupied area, and the required thickness; the positive electrode lead-out pin 5 is connected to the anode 2 using a metal ...

Abstract

The invention provides a flat electrolytic capacitor comprising an outer shell, an anode, electrolyte, a cathode, an anode pin and a cathode pin, wherein the anode, the electrolyte and the cathode are arranged on a plane in a laminated mode. Distinguished from a method that an anode, electrolyte and a cathode in the prior art are wound, the flat electrolytic capacitor solves the problem that an existing electrolytic capacitor is large in thickness. The electrolytic capacitor can be manufactured in a square shape or a slice shape, a traditional cylindrical structure is changed, and therefore the electrolytic capacitor is particularly suitable for electronic products requiring the small thickness of the electrolytic capacitor, and has wide application prospects.

Description

technical field [0001] The invention relates to an electrolytic capacitor, which is a planar or square electrolytic capacitor which is different from the existing cylindrical electrolytic capacitor. Background technique [0002] An electrolytic capacitor is a type of capacitance. The metal foil is the positive electrode (aluminum or tantalum), and the oxide film (aluminum oxide or tantalum pentoxide) that is close to the metal with the positive electrode is the dielectric. The cathode is made of conductive material and electrolyte (the electrolyte can be liquid or Solid) and other materials. Electrolytic capacitors are widely used in electronic circuits as filter elements and energy storage elements. The height and height are relatively large. In some occasions where the capacity is not very large but the thickness is very high, such as the power supply of some flat panel lights, the existing electrolytic capacitors cannot be used. There are also SMD electrolytic capacitors ...
