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 T521 High Voltage Polymer Electrolytic is designed for higher application voltages than the T520 KO-CAP. Developed for use on 12, 24, 28 and 48 volt DC voltage rails. The low ESR of the T521 provides high ripple current capability. KO-CAP's long-life reliability enables the T521 to be an ideal alternative to liquid-based electrolytic capacitors.
