A question about capacitor type and temperature limits
To be honest I have never seen an electrolytic capacitor with a minimum temperature rating. They and most capacitors DO have a maximum temperature rating. Most are rated to 85 C but for SMPS and other power devices you may need to buy 105 C rated versions. An 85 C capacitor exposed to 100 C will have a short life.

6 FAQs about [Capacitor temperature in capacitor cabinet]
What is the temperature coefficient of a capacitor?
The Temperature Coefficient of a capacitor is the maximum change in its capacitance over a specified temperature range. The temperature coefficient of a capacitor is generally expressed linearly as parts per million per degree centigrade (PPM/ o C), or as a percent change over a particular range of temperatures.
What are the temperature characteristics of ceramic capacitors?
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.
What temperature should a power capacitor be inside a cabinet?
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.
What is a normal working temperature for a capacitor?
The normal working range for most capacitors is -30 o C to +125 o C with nominal voltage ratings given for a Working Temperature of no more than +70 o C especially for the plastic capacitor types.
How does temperature affect the capacitance of a capacitor?
Changes in temperature around the capacitor affect the value of the capacitance because of changes in the dielectric properties. If the air or surrounding temperature becomes to hot or to cold the capacitance value of the capacitor may change so much as to affect the correct operation of the circuit.
What is a temperature compensating ceramic capacitor?
1. Temperature-compensating-type multilayer ceramic capacitors (Class 1 in the official standards) This type uses a calcium zirconate-based dielectric material whose capacitance varies almost linearly with temperature. The slope to that temperature is called the temperature coefficient, and the value is expressed in 1/1,000,000 per 1°C (ppm/°C).
