GREENVILLE, S.C. -- November 15, 2012

AVX Corporation, a leading manufacturer of passive components and interconnect
solutions, has developed two new high-reliability SMD tantalum chip capacitor
series for use in European aerospace applications. The TES Series multi-anode
molded tantalum chip capacitors and the TCH Series hermetically sealed
tantalum polymer chip capacitors both provide very low ESR, high capacitance,
and high voltage, as well as enable a significant payload reduction for power
supplies.

“The new TES and TCH Series SMD chip capacitors provide aerospace and other
high-reliability applications with all of the benefits of AVX’s tantalum
technology, which is a notable achievement because tantalum capacitors that
have been designed and approved for use in these industries are fairly
uncommon due to tantalum’s inherent sensitivity to the combination of humidity
and high temperatures,” said Dan Lane, product marketing manager at AVX.

AVX’s new TES Series multi-anode SMD molded tantalum chip capacitors feature
an improved high-reliability design and offer extremely low ESR, a capacitance
range of 1.0µF to 680µF, and a voltage range of 6.3 to 50VDC. Manufactured in
accordance with European Space Components Coordination (ESCC) standards, the
new TES Series provides several downsizing options, as well as higher
capacitance and lower ESR than comparable tantalum devices designed for use in
aerospace applications. The devices are also EPPL2 (European Preferred Parts
List) approved according to the new ESCC specification ESCC3012/004. Per ESCC
specifications, E case size TES Series capacitors use vertical multi-anode
internal construction to reduce the ESR to 30mOhm and D case size TES Series
capacitors utilize a mirror multi-anode design, which effectively reduces the
Equivalent Series Inductance (ESL) to half. TES Series SMD tantalum chip
capacitors are produced in AVX’s European Space Agency (ESA) qualified
manufacturing plant in Lanskroun, Czech Republic. Full QPL qualification is
scheduled for the third quarter of 2013.

AVX’s TCH Series hermetically sealed SMD tantalum polymer capacitors were
specifically designed for a mission-critical ESA project that required both
extremely high capacitance and very low ESR. Tantalum polymer capacitor
technology provides both high capacitance and very low ESR values, in addition
to lower derating and higher ripple current capabilities; however, due to its
sensitivity to the combination of high temperature and high humidity
conditions, has not been widely used in the aerospace industry. To suppress
humidity and oxidative degradation, AVX encased its tantalum polymer
capacitors in hermetically sealed SMD cases filled with an inert gas,
successfully eliminating the impact of environmental conditions and achieving
the excellent stability required for aerospace and other high-reliability
applications.

Featuring a low ESR conductive polymer electrode, AVX’s new TCH Series
hermetically sealed SMD tantalum chip capacitors provide high capacitance
values up to 680µF and high voltage of up to 100V, which makes them the
highest voltage space-grade SMD tantalum polymer capacitors currently on the
market. TCH Series capacitors are available in two case sizes: I case, which
measures 11.8mm x 6mm x 2.6mm and weighs 0.5g, and 9 case, which is comparable
to the CTC21D case size, measures 11.8mm x 12.5mm x 5.8mm, and weighs 2.4g.
Engineering samples of AVX’s TCH Series are currently available upon request
and will be made commercially available in the first quarter of 2013.

Series datasheet is available at http://www.avx.com/docs/catalogs/tch.pdf.
