Designers will often specify a maximum voltage ripple (%V ripple) to be around 5% to 10% to lessen the constraints on the capacitance value. This is also recommended to keep the capacitors functioning within a safe operating area. The change in current that flows through the DC capacitor will yield the change in charge (Δ q). An increased switching frequency will narrow

Rated voltage can be given for DC (direct current) and AC (alternating current). For film capacitors, both the DC and AC rated voltage is usually in the range from several tens to several hundred volts. High-voltage types for electric power systems have an AC voltage rating on the order of several thousand volts and higher.
The actual capacitance of film capacitors depends on the measuring frequency and the ambient temperature. Standardized conditions for film capacitors are a measuring frequency of 1 kHz and a temperature of 20 °C. The percentage of allowed deviation of the capacitance from the rated value is called capacitance tolerance.
The applicable standards specify the following conditions, regardless of the type of dielectric film. Film capacitors are not polarized and are suitable for handling an alternating voltage. Because the rated AC voltage is specified as an RMS value, the nominal AC voltage must be smaller than the rated DC voltage.
The maximum AC voltage (or DC voltage) that may be applied continuously to a capacitor at its upper category temperature. The maximum RMS voltage (in V) at specified frequency (mostly 50 Hz), that may be continuously applied to a capacitor at any operating ambient temperature below the rated temperature.
The breakdown voltage of film capacitors decreases with increasing temperature. When using film capacitors at temperatures between the upper rated temperature and the upper category temperature, only a temperature-derated category voltage V C is allowed. The derating factors apply to both DC and AC voltages.
The permissible pulse load capacity of a film capacitor is generally calculated so that an internal temperature rise of 8 to 10 K is acceptable. The maximum permissible pulse rise time of film capacitors which may be applied within the rated temperature range is specified in the relevant data sheets.
