固态电解电容与普通电容即液态铝质电解电容的最大差别在于采用了不同的介电材料，液态铝电容介电材料为电解液，而固态电容的介电材料则为导电性高分子材料。所以购买什么类型的电解电容就要看实际需求，让我们一起来了解下固态电解电容和液体电解电容的特点及应用范围。

　　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.
