The meaning is that the capacitance is 0.01uF. Firstly, it is necessary to understand several methods for identifying the capacitance of a capacitor. The first is direct identification, such as electrolytic capacitors with a capacity of 47uf and a capacitance withstand voltage of 25v. The second is to use the unit nf: for example, polyester capacitors, nominal 4n7, which is 4.7nf, converted to pf, which is 4700pf. There are also examples: 10n, which is 0.01uf; 33n, which is 0.033uf. The latter 63 refers to the capacitance withstand voltage of 63v. In addition, there is mathematical counting method. Like a ceramic capacitor with a nominal value of 103, the capacity is: 10X1000pf=0.01uf. If the nominal value is 473, it is 47X1000pf=0.047uf. (The following 4 and 3 both represent powers of 10). For example, 332=33X100pf=3300pf. The use of capacitors should operate under withstand voltage. Many low-quality products nowadays suffer from malfunctions due to the use of capacitors with insufficient voltage resistance (commonly capacitor bursting).
