Description
Technical field
The utility model relates to aluminium electrolytic capacitor.
Background technology
The requirement of present aluminium electrolytic capacitor applied environment is more and more higher, for example: frequency increase, increase, filtering and the charge-discharge characteristic of ripple current share etc., and aluminium electrolytic capacitor has been proposed new requirement.And the frequency characteristic of conventional aluminum electrolytic capacitor, anti-ripple current and charge-discharge characteristic have limitation.
The utility model content
The purpose of this utility model is to propose a kind of high frequency aluminium electrolytic capacitor of anti-the ripple, and it can solve the problem of high frequency characteristics difference.
In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:
The high frequency aluminium electrolytic capacitor of anti-the ripple, the capacitor core that it comprises aluminum hull and is positioned at aluminum hull, described capacitor core is by cathode foil, anode foil, electrolytic paper is reeled and is formed, electrolytic paper is between cathode foil and anode foil, the top of capacitor core also extends upward and is just leading chaff, the negative chaff of leading, and the negative other end of leading chaff extends to bottom and the folding bottom that is attached to capacitor core of capacitor core, just leading chaff is connected with cathode foil, negative lead chaff and be connected with anode foil, anode foil, the thickness of cathode foil is the 20-110 micron, and the density of electrolytic paper is 0.15-0.55g/cm
3, the thickness of electrolytic paper is the 20-60 micron.
Preferably, the negative folding part that is attached to the capacitor core bottom of leading chaff is connected with aluminum hull.
Preferably, anode foil is identical with the area of cathode foil.
The utlity model has following beneficial effect:
Can strengthen the bottom thermal diffusivity of aluminium electrolytic capacitor, and owing to negative lead chaff and be connected with aluminum hull, the negative ionic polymerization phenomenon of leading on the chaff is dispersed on the aluminum hull surface, and to reduce capacitor negative obstruction and heating punch-through of leading chaff under the ripple current effect, high frequency performance is good.
