Another feature of electrolytic CAPACITOR s, both aluminium and tantalum, is that most of them are polarized and require a DC bias for correct operation - a reverse bias may do damage and will certainly increase leakage (unpolarized electrolytic CAPACITOR s, which may be biased in either direction, do exist but they are uncommon, and considerably larger than the polarized variety).

电解电容还有一个特点，那就是绝大多数都是有极性的，其两端必须施加直流电压才能正常工作。如果极性接反，电容就可能损坏，其漏电流也会增加。无极性电解电容虽然已经问世，但是相比之下不常用，而且外形尺寸也比有极性电容大。
