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-3900± drawing.
TWA products are listed in DSCC 930ꢁ±, 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 3900±. Wet tantalums do not require the same
derating as solid tantalums. AVX recommends derating components by only
ꢁ0% 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.
