Capacitors will usually have a max rating to not exceed for ripple current, so this should be considered for the circuit design. Often times, the need arises to use several different value capacitors in parallel to target different frequencies or to simply get a higher total capacitance out of many lower ones.
When considering the capacitor size for a given application, parameters such as voltage, current ripple, temperature, and leakage current must be considered. Capacitor size selection is important, considering the physical size and capacitance aspects, as they affect circuit assembly and the performance variation of the circuit.
Different value capacitors help filter out different frequency noise. You can of course use multiple values to target multiple frequencies by placing a capacitor in parallel with other ones. You will see these all of the time near the supply voltage pins of chips.
The primary consideration for capacitor selection should be the nominal capacitance value. Knowing the application is important for determining the capacitance value. Either the designer calculates the capacitance or, in an integrated circuit application, the capacitance is recommended in the IC datasheet.
#1 Lesson: The major thing you need to know about capacitors is that they "love" to keep voltage steady, and will use current to make it happen. That may not make sense to you just yet, so let's take a look at a few other things next to make it much clearer. The key thing to know about capacitors is something called capacitance.
While having capacitors in series is not commonly done, you might run across it on occasion. Some designers will use this arrangement to allow for the voltage drop across the capacitors to be able to use lower voltage rated capacitors to save cost.This is generally not good design practice.
