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 listed in
DSCC 93026, 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 M39006.
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.
