However, if a large current causes a high temperature exceeding the specified value, the deterioration of the capacitor may be accelerated and cause a burnout. Self-heating of a capacitor depends on the dielectric material, the capacitance, the applied voltage, the frequency, the voltage waveforms and others factors.
If a current which causes self-heating is below the specified value, the capacitor deteriorates very little. However, if a large current causes a high temperature exceeding the specified value, the deterioration of the capacitor may be accelerated and cause a burnout.
Generally, the correlation of the frequency and voltage, which can be applied to the capacitor, is restricted by peak-to-peak voltage in the low frequency bands, and is restricted by self-heating in the high frequency bands. (See the following figure )
Since self-heating affects the characteristics of capacitors when ambient temperature changes, even under the same voltage conditions, perform the confirmation of self-heating at room temperature (25 °C).
2. Heat-generation characteristics of capacitors In order to measure the heat-generation characteristics of a capacitor, the capacitor temperature must be measured in the condition with heat dissipation from the surface due to convection and radiation and heat dissipation due to heat transfer via the jig minimized.
When pulse voltage with very short rising time or AC voltage with a high frequency is applied to a capacitors, even within the rated voltage the reliability of the capacitor may be influenced. When pulse voltage or AC voltage is applied to capacitors, even within the rated voltage, the capacitor may generate heat due to the current.

When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage rating of 10 Volts, as the voltage is the same across both capacitors, and you must not exceed the rating of either capacitors.
Parallel capacitors are capacitors that are connected across the same two points in a circuit, meaning they share the same voltage across their terminals.
