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 …

Equivalent voltage rating of Parallel connection of capacitors with ...
When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage rating of 10 Volts, as the voltage is the same across both capacitors, and you must not exceed the rating of either capacitors.

How do I increase the voltage limit by connecting same capacitors?
Connecting two identical capacitors in series, each with voltage threshold v and capacitance c, will result into a combined capacitance of 1/2 c and voltage threshold of 2 v.. However, it is far better to get a single capacitor that meets the higher voltage threshold on its own as combining capacitors in series will also lead to a higher Effective …

power supply
Here the second output capacitor is 0.1 uF and it is there to deal with high frequency noise. Note that having a large capacitor on the output can cause problems. If the input was shorted so that power was removed C4 would discharge back through the regulator. Depending on voltage and capacitor size this can cause damage.

In DC power sources, you will see large capacitors in parallel with the output used to filter the DC voltage output. In an "ideal" DC voltage source (like a fully charged car battery), putting capacitors in parallel with the battery terminals will initially change the total circuit current until the capacitor is fully charged wherein the current …

What is the effect of adding a capacitor and a battery in parallel?
Hence, we put capacitors in parallel to act as temporary sources of energy that the battery cannot provide. If the battery load took 100 mA pulses for a millisecond (now and then) and, we wanted the capacitor to not drop anything more than 0.3 volts (for example), we would need a capacitance of: -
