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 T530 high-capacitance polymer electrolytic expands the capacitance ranges of the T520 KO-CAP with a higher 125°C operating temperature and lower ESR options. The improved ESR levels allow for higher ripple current capability than the T520. The T530's reduced ESR, ripple current capability, and capacitance retention at higher frequencies provides the lowest total capacitance and most economical solution for high switching frequency DC power applications.
