KEMET Organic Capacitor (KO-CAP
®
) – Miniature
T528 Low ESL Polymer Electrolytic for CPU/GPU Decoupling
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 T528 low ESL Facedown Terminal Polymer Electrolytic
combines ultra-low ESR and high capacitance in a package
design that offers the lowest ESL in the market. This
series offers exceptional performance for high-speed
microprocessor, FPGA or ASIC decoupling designs. The
T528 utilizes a unique termination design that allows for a
reduction in the inductance loop area and comes in a low
profile 1.7 mm case height. This series offers improved
capacitance retention at frequencies of up to 1 MHz.
Benefits
• Low ESL <0.7 nH at 20 MHz
• Improved volumetric efficiency
• High frequency capacitance retention
• 100% accelerated steady state aging
• 100% surge current tested
• EIA standard case sizes
• Halogen-free Epoxy/RoHS Compliant
• Lead free 260°C reflow capable

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.
