Abstract: The invention relates to a coil type solid electrolytic capacitor containing solid organic polymer with high electrical conductivity as electrolyte and its manufacturing method. In the invention, such processes as oxidation, carbonization, immersing, chemical oxypolymerization, and so on are fully disclosed. The solid electrolytic capacitor of the invention has a pretty low equivalent series resistance (ESR), good impedance frequency properties, so can be used at a frequency above 1 MHz. And it has a high anti-ripple current capacity, wide applicable range of temperature, good temperature properties, large capacity, long life, and reliable performance, therefore can be widely applied in the fields of modern communication, computer, and high performance civilian and military electronic products.
