　Al (Polymer) Electrolytic Capacitor is chemical capacitor which the capacitance value make use of the chemical change. Based on the Electrolytic liquid/solid decrease by operation hours, the capacitance value will be decreased and tanδ will be increased, step by step.

铝电解电容是化学电容，利用化学变化来获得电容值。由于随着使用时间的增加电解液会逐渐减少，从而电容值会慢慢减少、介质损耗 (tanδ) 会慢慢增加。

　　Ceramic Capacitor is made by fine electronics ceramic (porcelain).Except for heavy-duty use like over specification, etc., there is no limitation for life time.

陶瓷电容是由精密电子陶瓷制作而成，除了在超出额定规格等超负荷情况下使用外，没有任何的寿命限制。
