The capacitors are charged to the peak voltage of the incoming AC waveform (or twice the peak value if used on the 120 V setting). For 10 % high mains voltage, this amounts to: As the two supply capacitors are identical and connected in series, the total capacitance of the series combination will simply be half of their individual capacitance.

Sometimes a manufacturer will not adhere to the EIA coding system, and mark the values directly on the capacitor. Here are some examples of such marking. 0.001K is a 0.001 uF capacitor with a ±10 % tolerance. 0.01Z is a 0.01 uF capacitor with a +80 % and -20 % tolerance. Example Markings and Values. Code:

Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a ...

As ceramic capacitors have less surface area because of their tiny size, their value is not written in the capacitor, instead an encoded code is written on them. By using this capacitor value calculator, we can calculate the value of that capacitor, or vice versa. For electrolytic capacitors, simply capacitance values are written on them.
