TWA Series
COTS-Plus Wet Electrolytic Tantalum Capacitor
The TWA series is an axial leaded wet electrolytic tantalum capacitor. High
capacitance cathode system allows high level of CV (Capacitance/Voltage) in
DSCC compatible case sizes.
This design includes a welded tantalum can and header assembly that
provides a hermetic seal to withstand harsh shock and vibration requirements
of MIL-PRF-39006.
Customized capacitance and voltage packages are possible and welcomed.
Contact the factory about design possibilities beyond those contained in this
datasheet.
These component may be supplied from either the U.S. or EU manufacturing
locations.

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.
*Not recommended for new designs, for new design use part number with Inspection level “S” – COTS-Plus
