TWA Series – DSCC 93026
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 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 harsh shock and
vibration requirements of 39006. Wet tantalums do not require the same
derating as solid tantalums. AVX recommends derating components by only
20% in order to enhance reliability.
Customized capacitance and voltage packages are possible and welcomed.
Contact the factory about design possibilities beyond those contained in this
datasheet.

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.
