The point here is, if you need to select a low-ESL capacitor with high self-resonance frequency, you can use a smaller capacitance, and just put multiple capacitors in parallel. The frequency response for a single low-ESL capacitor or multiple identical capacitors in parallel will be the same.
Dielectric absorption may be a more prominent consideration for low-voltage (thin dielectric) ceramic capacitors than larger voltages. Measurement Method. Short circuit the capacitors for 4 - 24 hours. Charge the capacitors to the rated voltage. Discharge the capacitors for 5 - 10 seconds through a 5-ohm resistor.

Electrolytic capacitor: Properties and operation
The melting point is the temperature at which a solid changes into a liquid. At its melting point, the disruptive vibrations of the particles of the solid overcome the attractive forces operating within the solid. ... Gases become solids at extremely low temperatures, and liquids will also become solid if the temperature is low enough. The ...

Capacitor-switching transients typically occur when a large capacitor on the high-voltage side of the power system (usually at the utility side) is ener- gized. This results in magnification of transients at low-voltage capacitors. The magnified transient at a low-voltage remote end can reach up to 400% of its rated values. Overvoltages.
