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 T525 Polymer Electrolytic is rated for 125°C operating temperatures, extending the category temperature of the standard T520 KO-CAP. The T525 delivers a higher temperature rating for applications that may exceed 105°C, while still offering the same advantages such as low ESR, high frequency capacitance retention, long life, and stable capacitance as other KO-CAPs.
