How To Read The Value of A Non-polar Capacitor

Three Number Code:
Three digit number codes are always in picofarads(pF)

The first two numbers are the first 2 digits. The third digit is the multiplier.














Example: What is the reading of this ceramic capacitor?


1 and 5 are the first two digits. Based on the table, 4 corresponds to 10 000.
Therefore, the capacitance of this capacitor is 150 000 pF.


What if you want to know the capacitance in nanofarads(nF)?
Remember: 1 pF = 1.0 X 10 ^-12 Farad
                  1 nF = 1.0 X 10 ^-9 Farad


 Get the difference of 12 and 9. It is 3.
 150 000 pF
 Move 3 spaces to the left and you'll get 150 nF.
