TBW Series
Tantalum Fused DSCC Dwg 04053 COTS-Plus Weibull Grade & Space Level
TBW Fused Tantalum Capacitors offer protection from
possible damaging short circuit failure modes. This is
accomplished with an internal fuse in series with the
capacitor. See the photograph on the right. The AVX
fused tantalum offers lower ESR limits than competi-
tive fused tantalum capacitors, and is available with
Weibull and surge testing per MIL PRF 55365.

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