TWA Wet Electrolytic Tantalum Capacitor
The TWA series is an axial leaded
wet electrolytic tantalum capacitor
and represents a new level of high
CV (capacitance / voltage)
previously unavailable in this
technology. TWA incorporates a
novel, very high capacitance
cathode system that allows for
higher CV designs, well beyond
values specified in the Mil-PRF-
39006 drawing. TWA products are
qualified to DSCC 93026 Rev. P,
which includes new high
capacitance / voltage ratings.
This design includes a welded
tantalum can and header
assembly that provides a hermetic
seal to withstand the harsh shock
and vibration requirements of
39006.
Customized capacitance and
voltage packages are possible and
welcomed. Contact the factory
about design possibilities beyond
those contained in this datasheet.

1/ At 125°C the rated voltage of the capacitors decreases to 66 2/3 of the 85°C rated voltage.
2/ The peak of the applied ac ripple voltage plus the applied dc voltage must not exceed the dc voltage rating of the
capacitors.
