APPLICATION NOTES
a) No continuous reverse voltage permissible.
b) The peak of the applied AC ripple and the applied DC
voltage must not exceed the DC voltage rating of the
capacitor.
c) Ripple current ratings by part number at 85 °C and 40 kHz
are included in the table. Ripple current correction factors
for other temperatures and frequencies are given on the
next page.
d) Transient reverse voltage surges are acceptable under
the following conditions:
the peak reverse voltage does not exceed 1.5 V and the
peak current times the duration of the reverse transient
does not exceed 0.05 As. In addition, the repetition
frequency of the reverse voltage surge is less than 10 Hz.
Vishay’s DLA 93026 capacitor represents a major
breakthrough in wet tantalum technology. Its unique
cathode system provides the highest capacitance per unit
volume. The design facilitates a doubling of capacitance,
lower ESR and higher ripple current rating compared
with conventional wet tantalum products. Moreover, the
DLA 93026 has the capacitance stability of a solid tantalum
capacitor and there are no circuit impedance restrictions.
The DLA 93026 is housed in an all tantalum, hermetically
sealed case and is manufactured to withstand hazardous
environments. The DLA 93026 is used widely in the defense
and aerospace industries and whenever there is a space
problem.
