Correct Use of Solid Tantalum Capacitors
Most tantalum capacitor failures are the result of leakage current or short circuits.
Please refer to Notes on Using the Tantalum Capacitors on pages 31 to 39 of this
brochure before designing tantalum capacitors into your system.

<Conductive Polymer Tantalum Capacitors>
“NeoCapacitors”
NEC has been manufacturing solid electrolyte
tantalum capacitors for more than 30 years. As
a result of NEC’s active research and develop-
ment programs, NEC capacitors offer the de-
signer the latest technology plus outstanding
performance.
NEC capacitors are used extensively in indus-
trial, commercial, entertainment, and medical
electronic equipment.
NEC has obtained ISO 9001 and QS9000 certifi-
cates of registration for capacitors.
The low-ESR conductive polymer tantalum ca-
pacitors are expected to meet an important
market need; ther are suited for DC/DC convert-
ers, video cameras, personal handy phones,
etc.

TANTALUM CAPACITORS
Description
NEC’s tantulum capacitors offer the designer advanced
technological design and excellent performance charac-
teristics for filtering, bypassing, coupling, decoupling,
blocking, and R C timing circuits. They are used exten-
sively in industrial, commercial, entertainment, and medi-
cal electronic equipment.
The tantalum capacitor is inherently very reliable and
there is significant evidence that this reliability improves
with age−perhaps indefinitely. Capacitance loss with age
and other problems often associated with liquid electro-
lytes are nonexistent in solid electrolyte tantalums.
A process used to fur ther improve the reliability of
tantalums is to burn them in at elevated voltages at 85°C
for extended periods of time, thus eliminating high leak-
age and other undesirable characteristics. This process
is done because solid electrolyte tantalum capacitors do
not conform to the exponential distribution of time or-
dered failures, but instead exhibit a constantly decreas-
ing failure rate.
If you specify NEC tantalums, you can feel confident that
you are getting the best available quality, reliability, and
price.
