Let's first recall the unit of capacitor unit capacitance: microfarad(μF), nanofarad(nF), and picofarad(pF).
Because the capacity of unit F (Fala) is too large, we usually see units of μF, nF and pF.
1F = 1000mF = 1000,000μF ；
1μF = 1,000nF = 1000,000pF；
1nF = 1000pF；
10nf = 10000pF；
Therefore, porcelain capacitor 10nf=10000pF is identified by 103, but not 103pF.
The 103 is capacitance value identification on capacitance. It is not 103 of the value. The 103 explanation of the industry is that the first two are valid numbers and the last bits are 10 times. The result is several times of effective number *10.
103 is: 10*10^3=10000. The ceramic capacitor 10nf is also often called the 103 ceramic capacitor.
Ceramic capacitor 10nf = 10000 pF, often called 103 ceramic capacitor, with 103 identification, but can not say 103pF, the ceramic capacitor 10nf is divided into high voltage porcelain capacitor and the safety of the plate capacitance, both are different pressure.
