Capacitor Specifications: what they mean
This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V. Can you use 20V, 25V or even higher? The answer is yes. It depends to your budget because the higher the voltage, the expensive the capacitor is.
