KEMET Organic Capacitor (KO-CAP^®) – High Reliability
T540/T541 COTS Polymer Electrolytic for High Reliability
Applications, 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 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 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 Series are the first polymer electrolytic capacitor
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.
