Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

The term "temperature coefficient" is best reserved for devices using class I dielectrics, which have a more or less linear temperature dependence, while the term "temperature characteristic" is more appropriate for capacitors using EIA class II and III dielectrics, which exhibit decidedly nonlinear shifts in capacitance with temperature.
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.
