Hybrid Capacitors are used in the power
conversion module on board the Space
Shuttle. This module allows
the shuttle to tap into the International
Space Station power
grid. With access to ISS power, the
shuttle is able to
remain docked at the ISS for longer. ThQ1 and
THQ3 Hybrid capcitors
were chosen for this application due to their
power density, high
reliability and environmental ruggedness.
Hybrid Capacitors are also used
on the
International Space Station for power
interruption buffering and
filtering of DC power. In other space
applications, Hybrid capacitors
are specified in a number of Satellite
programs, providing pulse and
back up power. Rigorous screening and
qualifications have demonstrated
the performance and reliability of Evans
Hybrid Capacitors for use in
manned and unmanned space applications.
Hybrid Capacitors utilize Evans
patented
Hybrid® Capacitor technology, which
provides very high power
density compared with other tantalum
capacitors. Hybrid Capacitors have
a tantalum pentoxide dielectric, in
conjunction with a Ruthenium oxide
cathode, providing high single cell voltages
(high power density for
pulse applications) and high capacitance (high
energy density for power
back up applications).

Capacitors and
capacitor banks can be found here. For more
