T540 COTS polymer capacitor

KEMET Organic Capacitors (KO-CAP) are solid electrolytic capacitors 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 T540 COTS Polymer Electrolytic offers the same performance advantages as other KO-CAP series with screening options associated with high reliability ("Hi-Rel") applications. These Commerical-Off-The-Shelf (COTS) grade components are built with a tin-lead (SnPb) termination finish and offer several surge current screening options. The recommended application derating for these capacitors is 10 – 20%, rendering them suitable for application voltages from 2.25 to 50 VDC.
