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 screening options. The recommended application derating electrolytic capacitor with a conductive polymer cathode for these capacitors is 10 20%, rendering them suitable for capable of delivering very low ESR and improved application voltages from 2.5 to 63 VDC. capacitance retention at high frequencies. KO-CAP combines the low ESR of multilayer ceramic, the high These are the fi rst polymer electrolytic capacitors available capacitance of aluminum electrolytic, and the volumetric with failure rate options as defined by KEMET s KO-CAP efficiency of tantalum into a single surface mount package. Reliability Assessment method. This method utilizes Unlike liquid electrolyte-based capacitors, KO-CAP accelerated conditions (voltage and temperature) applied to has a very long operational life and high ripple current board-mounted samples to assess long term device reliability. capabilities. 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 HRA Polymer Electrolytic offers the same performance The KO-CAP Reliability Assessment method was developed advantages as other KO-CAP series with screening options as a result of over 10 years of research and is described in associated with high reliability (Hi-Rel) applications. numerous papers available on www.kemet.com.

When extreme temperatures and humidity are taken into account, polymer capacitors offer a number of advantages over other types of capacitors. KEMET continues to investigate the behavior of polymer capacitors in extreme conditions. If you have questions about using these capacitors in a specific environment or application, we suggest you contact your local KEMET representative or Field Application Engineer.
