yes that is true for capacitance value, how about the working voltage on it, some capacitors marked with 2A104J in which 2A stands for working voltage of 100 volts, 104 is the capacitance value, J is the tolerance. if the capacitor marked only with 220Pf? how to find out the working voltage on it.If they have 3 numbers then the first 2 are the first 2 digits of the value and the last is the number of zeros to add. So, 474 would be 470,000 pF = 0.47uF.
