Technical Summary and
Application Guidelines
2.1 RIPPLE RATINGS (A.C.)
In an a.c. application heat is generated within the capacitor
by both the a.c. component of the signal (which will depend
upon the signal form, amplitude and frequency), and by the
d.c. leakage. For practical purposes the second factor is
insignificant. The actual power dissipated in the capacitor is
calculated using the formula:
and
and substituting
where

Where P is the maximum permissible power dissipated as
listed for the product under consideration (see tables).
However care must be taken to ensure that:
1. The d.c. working voltage of the capacitor must not be

Historical ripple calculations.
Previous ripple current and voltage values were calculated
using an empirically derived power dissipation required to
give a 10°C rise of the capacitors body temperature from
room temperature, usually in free air. These values are shown
in Table I. Equation 1 then allows the maximum ripple current
to be established, and Equation 2, the maximum ripple
voltage. But as has been shown in the AVX article on thermal
management by I. Salisbury, the thermal conductivity of a
Tantalum chip capacitor varies considerably depending upon
how it is mounted.
