Kemet KO-CAP High Reliability Polymer Capacitors

The KEMET Organic Capacitor (KO-CAP) is a solid electrolytic capacitor with a conductive polymer cathode capable of delivering ultra-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.

T540 and T541 Series 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 over 10 years of research and is described in numerous papers available on www.kemet.com.
