高分子有机半导体固体电容器(POSCAP)是一种正极采用钽烧结体或铝箔,负极采用具有高导电性的高分子材料的电容器,其卓越的高频特性及低ESR深受好评,被广泛用于笔记本电脑,电源模块等的开关电源的输入输出端。 POSCAP的构造基本上与普通钽电解电容器相同,的不同是电解质采用了导电性高分子材料。正极采用钽烧结体充分发挥钽的高介电系数特性。不但实现了小型电容器的大容量化,同时负极采用导电性高分子材料实现了更低的ESR及可靠性方面的改善。POSCAP的额定电压2.5V-25V,容量2.2μF -1000μF,ESR达5mΩ。推荐使用电压为额定电压10V以下的产品,电压降低10%、额定电压10V以上的产品,电压降低20%,而普通钽电解电容器的电压降低高达50%。
