KEMET Organic Capacitor (KO-CAP
®
)
T52X/T530 Polymer Electrolytic Capacitors
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 T52x/T530 Series provides the widest range of voltages, capacitance and case size options in the KO-CAP family and is
suitable for general purpose DC applications for up to 48 volt DC voltage rails.

T52x/T530 Polymer Electrolytic Capacitors
Reliability
KO-CAP capacitors have an average failure rate of 0.5 %/1,000 hours at category voltage, U
C
, and category temperature, T
C
.
These capacitors are qualified using industry test standards at U
C
and T
C
. The minimum test time (1,000 or 2,000 hours) is
dependent on the product series.
The actual life expectancy of KO-CAP capacitors increases when application voltage, U
A
, and application temperature, T
A
,
are lower than U
C
and T
C
. As a general guideline, when U
A
< 0.9 * U
C
and T
A
< 85°C, the life expectancy will typically exceed
the useful lifetime of most hardware (> 10 years).
The lifetime of a KO-CAP capacitor at a specific application voltage and temperature can be modeled using the equations
below. A failure is defined as passing enough current to blow a 1-Amp fuse. The calculation is an estimation based on
empirical results and is not a guarantee.
