固態電解電容與普通電容即液態鋁質電解電容的最大差別在于采用了不同的介電材料，液態鋁電容介電材料為電解液，而固態電容的介電材料則為導電性高分子材料。所以購買什么類型的電解電容就要看實際需求，讓我們一起來了解下固態電解電容和液體電解電容的特點及應用范圍。
The biggest difference between solid-state electrolytic capacitors and ordinary capacitors, i.e. liquid aluminum electrolytic capacitors, is the use of different dielectric materials. The dielectric materials of liquid aluminum capacitors are electrolyte, while the dielectric materials of solid-state capacitors are conductive polymer materials. So what type of electrolytic capacitor to buy depends on the actual demand, let's understand the characteristics and application range of solid-state electrolytic capacitor and liquid electrolytic capacitor.
