Why Low ESR Matters in Capacitor Design
For medium and high voltage applications, low loss aluminum electrolytic capacitors are required. Low ESR capacitors have less power losses and internal heating problems as compared to high ESR capacitors. Apart from lowering performance, high ESR values reduce the life of an aluminum electrolytic capacitor. In addition, a low ESR …
Aluminum electrolytic capacitor
Because the thickness of the effective dielectric is proportional to the forming voltage, the dielectric thickness can be tailored to the rated voltage of the capacitor. For example, for low voltage types a 10 V electrolytic capacitor has a dielectric thickness of only about 0.014 μm, a 100 V electrolytic capacitor of only about 0.14 μm.

The Complete Low-ESL Capacitor Guide
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.
Supercapacitor
Standard supercapacitors with aqueous electrolyte normally are specified with a rated voltage of 2.1 to 2.3 V and capacitors with organic solvents with 2.5 to 2.7 V. Lithium-ion capacitors with doped electrodes may reach a rated voltage of 3.8 to 4 V, but have a low voltage limit of about 2.2 V. Supercapacitors with ionic electrolytes can ...
What happens if I connect a low voltage rated capacitor to a high voltage?
For a capacitor, one of the limits is keeping the voltage low enough that the capacitor dielectric stays intact. As you increase the terminal voltage, the electric stress increases across the dielectric, and eventually, it breaks down. When that happens, you don''t have a capacitor any more.

What does the Voltage Rating on a Capacitor Mean?
Some say a good engineering practice is to choose a capacitor that has double the voltage rating than the power supply voltage you will use to charge it. So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it''s best to use a 50 volt-rated capacitor.
Best audiophile capacitors for crossover design
2 x 50µF in parallel does give 100µF, but this is unrelated to supply voltage, or the capacitor voltage rating. In any parallel circuit there is only one voltage, so all capacitors will need a voltage rating higher than the circuit voltage. Regards, Richard

Electrolytic capacitor
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Because of their very …
Ceramic Capacitor Voltage Rating
That means, for example, if the actual capacitor voltage is 50V, select a capacitor rated for at least 100 V. It is a common practice in electronic component selection to derate the ceramic capacitor voltage rating by 50% to prevent explosion as well as VCC. In any electronic circuit designed with ceramic capacitors, this trend should be followed.
