KEMET's solid tantalum chip family that offers optimal
performance in applications with operating tempera-
tures of up to 150° C. Advancements in materials and
testing have allowed for the introduction of this series
which delivers a reliability level of 0.5% per 1000 hours
at rated voltage at rated temperature.

solid tantalum capacitor technology. KEMET’s T510
Series offers low ESR in the popular EIA 7343-43 and
7360-38 case sizes. The ultra-low ESR and high ripple
current capability make the T510 an ideal choice for
SMPS filtering and power decoupling of today’s high
speed microprocessors.
platform that incorporates multiple capacitor elements,
in parallel, inside a single package. This unique
assembly, combined with KEMET’s superior process-
ing technology, provides the best combination of high
CV, low ESR, and small size in a user friendly, molded,
surface mount package.
Tantalum capacitor, with a Ta anode and Ta
dielectric. However, a conductive, organic, polymer
replaces the MnO2 as the cathode plate of the
capacitor. This results in very low ESR and improved
cap retention at high frequency. The KO-CAP also
exhibits a benign failure mode, which eliminates the
ignition failures that can occur in standard MnO2
Tantalum types. Note also that KO-CAPs may be
operated at voltages up to 90% of rated voltage for

tilayer ceramic caps (low ESR and high frequency
cap retention), aluminum electrolytics (benign failure
mode), and proven solid tantalum technology (volu-
metric efficiency, surface mount capability, and no
wearout mechanism). The KO-CAP can reduce
component counts, eliminate through-hole assem-
bly by replacing cumbersome leaded aluminum
capacitors, and offer a more cost effective solution
to high-cost high-cap ceramic capacitors. These
benefits allow the designer to save both board
space and money. See pages 42-52 for complete
details.
Polymer Capacitor rated up to 125ºC. This part type
was introduced as Lead (Pb) Free and offers the

the depth that the signal must penetrate, this parallel
arrangement reduces the ESR further still to achieve
the highest capacitance and lowest ESR of any other
type of SMT capacitor with typical ESR values as low
as 5 milliohms. With the reduced ESR, the enhanced
capacitance retention in higher frequencies results in
the lowest total capacitance solution and provides for
the most economical solution in high power applica-
tions.
