Technical Summary and
Application Guidelines
SECTION 1
ELECTRICAL CHARACTERISTICS AND EXPLANATION OF TERMS
1.1 CAPACITANCE
1.1.1 Rated capacitance (C
This is the nominal rated capacitance. For tantalum capaci-
tors it is measured as the capacitance of the equivalent
series circuit at 20°C using a measuring bridge supplied by a
0.5Vpk-pk 120Hz sinusoidal signal, free of harmonics with a
maximum bias of 2.2Vd.c.
1.1.2 Capacitance tolerance.
This is the permissible variation of the actual value of the
capacitance from the rated value. For additional reading,
please consult the AVX technical publication “Capacitance
Tolerances for Solid Tantalum Capacitors”.
1.1.3 Temperature dependence of capacitance.
The capacitance of a tantalum capacitor varies with temper-
ature. This variation itself is dependent to a small extent on
the rated voltage and capacitor size.
1.1.4 Frequency dependence of the capacitance.
The effective capacitance decreases as frequency increases.
Beyond 100KHz the capacitance continues to drop until res-
onance is reached (typically between 0.5 - 5MHz depending
on the rating). Beyond the resonant frequency the device
becomes inductive.

1.2 VOLTAGE
1.2.1 Rated d.c. voltage (V
This is the rated d.c. voltage for continuous operation at
85°C.
1.2.2 Category voltage (V
This is the maximum voltage that may be applied continu-
ously to a capacitor. It is equal to the rated voltage up to
+85°C, beyond which it is subject to a linear derating, to 2/3
V
1.2.3 Surge voltage (V
This is the highest voltage that may be applied to a capaci-
tor for short periods of time in circuits with minimum series
resistance of 1Kohm. The surge voltage may be applied up
to 10 times in an hour for periods of up to 30 seconds at a
time. The surge voltage must not be used as a parameter in
the design of circuits in which, in the normal course of oper-
ation, the capacitor is periodically charged and discharged.
1.2.4 Effect of surges
The solid Tantalum capacitor has a limited ability to withstand
voltage and current surges. This is in common with all other
electrolytic capacitors and is due to the fact that they oper-
ate under very high electrical stress across the dielectric. For
example a 25 volt capacitor has an Electrical Field of 147
KV/mm when operated at rated voltage.
