未核实，仅供参考T520系列——有机聚合钽电容
KO-CAP是一种采用Ta质阴极和Ta2O5为电介质的钽电容。但该电容器中由一种具导电性的有机聚合物代替MnO2作为电容的阴极极板。这一改变实现了很低的等效串联电阻和高频条件下更高的电容残留量。KO-CAP电容还具有良好的故障模式，该模式可排除各种标准MnO2钽型电容会遭遇的点火故障。值得注意的还有，额定电压≤10伏的元件可在达到额定电压90％的条件下工作；额定电压>10伏的元件只能在不超过额定电压的80％的条件下工作；这些情况下KO-CAP电容的可靠度于在达到50％额定电压条件下工作的标准钽电容的可靠度相当甚至更高。
T520系列集合了多层陶瓷电容容量（低等效串联电阻和高频电容残留值，铝电解电容器（良好的故障模式），和经认可的表面贴装技术（体积上的有效利用空间、表面贴装性能及不磨损机械装置）的最佳特点。KO-CAP电容可减少元件数量，通过取代笨重的含铅铝电容来消除通孔装配（安装），并针对高成本、大容量陶瓷电容提供一个成本效益更高的解决方案。这些优点使设计者能既节省钱又节省插件板空间。

POLYMER CAPACITORS
T520 SERIES—Conductive Polymer
The Kemet Organic Capacitor (KO-CAP) is a Tantalum capacitor, with a Ta anode and Ta2O5 dielectric. However, a conductive,organic,polymer replaces the MnO2 as the cathode plate of the capacitor. This results in very low ESR and improved cap retention at high frequency. The KO-CAP also exhibits a benign failure mode, which eliminates the ignition failures that can occur in standard MnO2 Tantalum types. Note also that KO-CAPs may be operated at voltages up to 90% of rated voltage forpart types with rated voltage≤?10 volts and up to 80% of rated voltage for part types > 10 volts with equivalent or better reliability than standard tantalums operated at 50% of rated voltage.
The T520 series captures the best features of multilayer ceramic caps (low ESR and high frequency cap retention), aluminum electrolytics (benign failure mode), and proven solid tantalum technology (volumetric efficiency, surface mount capability, and no wearout mechanism). The KO-CAP can reduce component counts, eliminate through-hole assembly by replacing cumbersome leaded aluminum capacitors, and offer a more cost effective solution to high-cost high-cap ceramic capacitors. These benefits allow the designer to save both board space and money. See pages 42-52 for complete details.
