TWA Series
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) previ-
ously 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 listed in DSCC 93026
Rev. P, which includes new high
capacitance / voltage ratings.
This design includes a welded tan-
talum can and header assembly
that provides a hermetic seal to
withstand the harsh shock and
vibration requirements of 39006.
Customized capacitance and volt-
age packages are possible and
welcomed. Contact the factory
about design possibilities beyond
those contained in this datasheet.

1/ At 125ºC the rated voltage of the capacitors decreases to 66 2/3 of the 85ºC 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.

All technical data relates to an ambient temperature of +25ºC. Capacitance and DF are measured at 120Hz, 0.5RMS with DC bias of 2.2V. DCL is measured at
rated voltage after 5 minutes.
NOTE: AVX reserves the rights to supply higher voltage rating in the same case size, to the same reliability standards.
