KEMET Organic Capacitor (KO-CAPR)–Industrial
T520 Low ESR Polymer Electrolytic,2–25VDC

Overview
The KEMET Organic Capacitor (KO-CAP) is a solid electrolytic
capacitor with a conductive polymer cathode capable of
delivering very low ESR and improved capacitance retention at
high frequencies. KO-CAP combines the low ESR of multilayer
ceramic, the high capacitance of aluminum electrolytic and the
volumetric efficiency of tantalum into a single surface mount
package. Unlike liquid electrolyte-based capacitors, KO-CAP has
a very long operational life and high ripple current capabilities.

The T520 Low ESR Polymer Electrolytic provides the widest range
of voltage, capacitance and case size options in the KO-CAP
family. Suitable for general purpose DC applications up to 12.8
volts, the T520 is ideal for DC-to-DC converters, bulk decoupling
and hold-up.

Benefits
Extremely low ESR
Volumetrically efficient
High frequency capacitance retention
100% accelerated steady state aging
100% surge current tested
EIA standard case sizes
Halogen-Free Epoxy/RoHS Compliant

Applications
Typical applications include DC/DC converters, notebook PCs,
portable electronics, telecommunications (mobile phone and base station),displays,SSD,HDD and USB.
應用
典型的應用包括直流/直流轉換器，筆記本電腦，便攜式電子產品，電信（移動電話和基站），顯示屏，SSD，HDD和USB。
 

鉭質電容係為一種採用鉭金屬做為介電質的電解電容。

以鉭金屬粉的表面所形成的五氧化二鉭(Ta2O5)薄膜為其介電質。

和其他電容相比，鉭質電容的特長在於能夠製造出體積更小、容量更大的產品。

和大容量的陶瓷電容產品相較之下，鉭質電容在各種電壓、溫度下的容量均十分穩定。

鉭質電容不像鋁電解電容必須使用電解液，因此不會有電解液外漏或是乾涸的問題。

其性能不易因時間經過而產生變化，因此鉭質電容並沒有界定其使用壽命。

鉭質電容，與積層陶瓷電容(MLCC)、鋁質電容皆為電容器，功能類似，

用於在電器中儲存能量；差別在於使用的材料為稀有金屬鉭，

比起陶瓷粉所製的MLCC，容質更高、特性也更佳，且體積可縮小化，

用在需要有高效能、小體積和高信度的設備上，手機、USB裝置等，在資料傳輸裝置上若用鉭質電容，傳輸的效率會更佳。

助聽器、心率調節器，汽車的安全汽囊、GPS、點火裝置和防鎖死煞車系統，

到手提電腦、手機、遊戲機、數位相機等。
