Problems solved by technology

High-temperature low-impedance long-life electrolytic capacitor is a kind of capacitor. At present, the technology of high-temperature low-impedance long-life electrolytic capacitor is developing rapidly, and its products are updated quickly. However, the life of electrolytic capacitors currently on the market is not long. Due to overvoltage, reverse Voltage, high temperature, rapid charging and discharging, etc., one of the biggest influences is temperature, because the higher the temperature, the faster the evaporation loss of the electrolyte

Abstract

The invention discloses a high-temperature low-impedance long-service life electrolytic capacitor, which comprises an aluminum cylinder; one end of the cylinder is opened; an electrolyte layer is arranged in the cylinder; the opened end of the cylinder is provided with a sealing layer which seals the cylinder; an anode is penetrated in the sealing layer and is conducted with the electrolyte layer; and a cathode is arranged outside the sealing layer and is conducted with the cylinder. The conducting performance of the high-temperature low-impedance long-service life electrolytic capacitor is enhanced by adopting electrolyte paper and conductive paper arranged at intervals; the sealing performance of the high-temperature low-impedance long-service life electrolytic capacitor is enhanced through the arrangements of a groove and a convex edge; and the service life of the capacitor is prolonged due to excellent sealing effect of the high-temperature low-impedance long-service life electrolytic capacitor.

Description

Technical field [0001] The present invention relates to capacitors, in particular to a high-temperature, low-impedance and long-life electrolytic capacitor with good sealing effect and long service life. Background technique [0002] In the prior art, a capacitor is an indispensable electronic component in the electronics and power fields. Capacitors are widely used in power supply filtering, signal filtering, signal coupling, resonance, DC blocking and other circuits, making an indelible contribution to the rapid development of modern electronic technology. High-temperature, low-impedance and long-life electrolytic capacitors are one of the capacitors. At present, the technology of high-temperature, low-impedance and long-life electrolytic capacitors is developing rapidly, and its products are quickly updated. However, the electrolytic capacitors currently on the market do not have a long life. Voltage, high temperature, rapid charge and discharge, etc., one of the biggest effe...
