Advanced Polymer Electrolytic Capacitors Task
04-067
Description Commercial introduction of new
polymer materials for use as the electrolyte in
solid tantalum and solid aluminum electrolytic
capacitors is underway. The polymer materials
are a radical change from the electrolytes
traditionally used. These new technologies
promise to offer improvements in volumetric
efficiency and performance. This task will
review the published literature for both tantalum
polymer and aluminum polymer electrolytic
capacitors. Visits will be made to manufacturers.
A technical report will be provided documenting
the technology readiness level of both capacitor
technologies. Recommendations will be made
regarding additional analyses necessary to
migrate these technologies to a readiness level
suited for NASA applications. NASA
Projects/designers will be surveyed to identify
the level of interest and applicability of these
technologies to NASA systems.
Benefits The polymer electrolytic capacitors
may offer several performance advantages over the
traditional electrolytic capacitors including
higher volumetric efficiency, reduced equivalent
series resistance, better frequency response, and
less catastrophic failure modes. light.
