Abstract

The invention discloses a square high-energy tantalum hybrid capacitor and a manufacturing technology of the square high-energy tantalum hybrid capacitor. The square high-energy tantalum hybrid capacitor comprises a capacitor cavity which is composed of a square tantalum outer shell and a square insulating tantalum sub-cover, wherein the capacitor cavity is filled with anode tantalum cores which are made of high-specific-volume tantalum powder in a pressed mode, cathode layers coated by RuO2, and a plurality of isolating layers in sequence. According to the square high-energy tantalum hybrid capacitor and the manufacturing technology of the square high-energy tantalum hybrid capacitor, the capacity of the square high-energy tantalum hybrid capacitor is improved, material cost is reduced, and manufacturing is convenient.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a square tantalum hybrid capacitor and its manufacturing process. Background technique [0002] The texture of tantalum is very hard, and tantalum is malleable and can be drawn into thin filaments to make thin foil. Its coefficient of thermal expansion is small. Tantalum has very good chemical properties and is extremely resistant to corrosion. No matter under cold or hot conditions, it does not react to hydrochloric acid, concentrated nitric acid and "aqua regia". It can be used to make evaporation vessels, etc., and can also be used as electrodes, rectifiers, electrolysis, and capacitors for electronic tubes. [0003] Tantalum forms a stable anodic oxide film in acidic electrolyte. Electrolytic capacitors made of tantalum have the advantages of large capacity, small size and good reliability. Manufacturing capacitors is the most important use of tantalum. [0004] The existing cir...
