Problems solved by technology
The upper limit of the operating temperature of conventional leaded aluminum electrolytic capacitor products is generally around 105°C. This temperature limitation makes the capacitor have certain limitations in the actual use process.
In power supply equipment, the operating temperature of capacitors often exceeds 105°C, and when conventional leaded aluminum electrolytic capacitors are used in the field of power supply equipment, they are prone to failure due to excessive temperature and have a short service life.

Embodiment Construction
[0026] The present invention will be further described below in conjunction with accompanying drawing.
[0027] The invention provides a leaded aluminum electrolytic capacitor, comprising:
[0028] shell1;
[0029] The core 2, the core 2 is arranged inside the shell 1, and it is soaked in the electrolyte solution inside the shell 1, and the electrolyte of the electrolyte solution adopts nano-scale long carbon chain branched organic ammonium salt.
[0030] Specifically, in the field of capacitors, the limitation of the operating temperature of the capacitor is actually mainly due to the limitation of the operating temperature of its electrolyte, so improving the stability of the electrolyte of the capacitor in a high temperature environment is the most effective way to enhance the high temperature resistance of the capacitor There is one of the means.
[0031] Using nano-scale long carbon chain branched organic ammonium salt as the electrolyte of the electrolyte, the upper te...

Abstract
The invention provides a lead-type aluminum electrolytic capacitor, which comprises a shell and a core, the core is arranged in the shell and is soaked in an electrolyte in the shell, and the electrolyte of the electrolyte adopts nanoscale long-carbon-chain branched chain type organic ammonium salt. On the basis of the technical scheme of the invention, the upper limit of the use temperature range of the capacitor is improved, and the stability of the capacitor is improved; therefore, the aluminum electrolytic capacitor has stronger high temperature resistance and more stable performance, and has reliable performance and longer service life when being applied to a high-temperature use environment in the field of power supplies.
Description
technical field [0001] The invention relates to the technical field of capacitors, in particular to a leaded aluminum electrolytic capacitor. Background technique [0002] As a common component on the electronic circuit of electrical equipment, leaded aluminum electrolytic capacitor plays the role of filtering, bypassing, coupling, decoupling, and switching. The upper limit of the operating temperature of conventional leaded aluminum electrolytic capacitor products is generally around 105°C. This temperature limitation makes the capacitor have certain limitations in the actual use process. In power supply equipment, the operating temperature of capacitors often exceeds 105°C, and when conventional leaded aluminum electrolytic capacitors are used in the field of power supply equipment, they are prone to failure due to excessive temperature and have a short service life. [0003] Therefore, in the field of power supply equipment, it is necessary to propose a capacitor that ca...
