Increase capacitor voltage rating by using multiple capacitors?
$begingroup$ @Majenko: The point is to reduce the high frequencies enough so that the active circuit in a voltage regulator can handle the remaining ones. Usually up to a few 10s of kHz is OK. For example, I often use some 950nH 600mOhm 200mA 0805 ferrites. With 22uF capacitance following these, you get one pole at 12 kHz from the R-C action, and …
High-voltage capacitor in a low-voltage system
A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it.

What is Capacitor and How Does It Work ?
Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of …
How can a voltage across a capacitor be greater than the total voltage …
In fact, this is the basis of a circuit known as a boost converter, whose job is to make a higher voltage from a lower one. Consider all currents zero at start, with the capacitor voltage V1. When the switch closes, a constant voltage is applied to the inductor, so current increases linearly thru the inductor.
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.
How to Test a Capacitor With a Multimeter?
Connect the voltmeter to the capacitor, and then apply an AC voltage to the capacitor. If the capacitor is good, the voltmeter should show a small AC voltage. If the voltmeter shows a large AC voltage, then the capacitor is bad. How many ohms should a capacitor have? A capacitor should have a very low resistance, usually below 1 ohm.
