$begingroup$ @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 another two poles at 35 …

For example, if a capacitor rated at 200V is connected to a series of capacitors rated at 500V in parallel, the maximum voltage rating of the whole rating will only be 200V even if most capacitors in the system were rated at 500V, just because of one capacitor rated at 200V.
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 Series Resistance (ESR).
