KEMET Organic Capacitor (KO-CAP®) – High Reliability
T540/T541 High Reliability Series (HRA) Polymer Electrolytic, 2.5 – 63 VDC
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 HRA Polymer Electrolytic offers the same performance advantages as other KO-CAP series with screening options associated with high reliability (Hi-Rel) applications. These HRA grade components offer several surge current
screening options. The recommended application derating for these
capacitors is 10 – 20%, rendering them suitable for application
voltages from 2.5 to 63 VDC.
These are the first polymer electrolytic
capacitors available with failure rate options as defined by KEMET's KO-CAP Reliability Assessment method. This method utilizes accelerated conditions (
voltage and temperature) applied to board-mounted samples to assess long term device reliability. The failure rates available are B (0.1% per 1,000 hours), C (0.01% per 1,000 hours), and D (0.001% per 1,000 hours). The KO-CAP Reliability Assessment method was developed as a result of ove...
