maximum operating temperature is 105 °C. Polypropylene fits many of the applications polyester misses. It even complements polyester in wide temperature applications: capacitance decreases with temperature at about the same rate as capacitance increases for polyester capacitors, so a polypropylene capacitor in parallel with a polyester spawns
Average increase of temperature in the interior of the cabinet will be then 19 oC. If room temperature is 30o C, temperature inside of the cabinet will be 49 oC, lower than the maximum 50oC recommended by the IEC 831 Standard for power capacitors.
*2 Maximum operating temperature: By design, maximum ambient temperature including self-heating 20°C MAX that allows continuous use of capacitors. The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C. Figure 1 below shows typical temperature characteristics.
Heating to 200°C for 10 minutes for a second time probably won't ruin your capacitors, but it may reduce their life. The most important, however, is the peak temperature phase, where the temperature goes for a short time (about half a minute) to about 250°C, depending on package volume.
For long periods of storage keep capacitors at cool room temperatures and in an atmosphere free of halogen gases like chlorine and fluorine that can corrode aluminum. Storage temperature ranges are from –55 ºC to the upper limit of the operating-temperature ranges. Sources: Capacitor Selection Guide - KEMET (.PDF)
Largely the formation voltage sets the high-temperature limit. Higher formation voltages permit higher operating temperatures but reduce the capacitance. The low-temperature limit of an electrolytic capacitor is set largely by the cold resistivity of the electrolyte.
The temperature characteristics of ceramic capacitors are those in which the capacitance changes depending on the operating temperature, and the change is expressed as a temperature coefficient or a capacitance change rate. There are two main types of ceramic capacitors, and the temperature characteristics differ depending on the type. 1.

If room temperature is 30ºC, temperature inside of the cabinet will be 49ºC, lower than the maximum 50ºC recommended by the IEC 831 Standard for power capacitors. If outside temperature is expected to be higher, following solutions can be used: • Enlarge the size of the cabinet in order to have a bigger refrigeration surface
If the ambient temperature is too high, the heat generated when the capacitor works can not be dispersed; If the environment is too low, the technical conditions of the capacitor, the operating temperature of the capacitor is generally 40℃ as the upper limit.

Test by applying the specified multiple of rated voltage for one minute through a current-limiting resistance of 100 per volt. As an illustration, to test a Type DPM capacitor rated 250 Vdc and 175% dielectric strength, apply 438 Vdc …
In general, tantalum and ceramic capacitors are the most frequently used for applications operating at temperatures above 175 oC. Most MLCC high temperature offerings are designed to operate at maximum temperatures of 150oC or 200oC.
Also it should be noted that an X7R or C0G (which generally have higher operating temperature ratings) do not degrade with time and support 125C operating ranges in most cases. So I would go with a higher temperature rated part or contact the manufacturer. If cost is an issue then finding the rating would be a good idea, if cost is not then just go with the …

capacitor should be chosen with a maximum specified temperature greater than the operating temperature of the application; this will increase the capacitor useful lifetime. All Kendeil capacitors maintain good behaviour under any climatic conditions when operating conditions are within the design specifications limits of each product type.
Use the capacitors according to the specified operating temperature range. If used the capacitor outside the maximum rated temperature will considerably shorten the life or cause the capacitor to vent. Usage at room ambient will ensure longer life. (5) Leakage Current The leakage current shall be within specified levels. When capacitors are ...

Higher formation voltages permit higher operating temperatures but reduce the capacitance. The low-temperature limit of an electrolytic capacitor is set largely by the cold resistivity of the electrolyte. The higher cold resistivity increases the capacitor''s ESR 10 to 100 fold and reduces the available capacitance.
