The post “capacitor number code” lists Non Polarized capacitors number codes with their values in Pico Farad (pF), Nano Farad (nF), and Micro Farad (µF) respectively. Also, it teaches you how to calculate the value by yourself for knowledge sake. This is because you may not be close or in position of the number codes and values of the capacitors table which I provide below. Beside, as an Engineer concern you should be able to calculate this type of capacitors’ values.
First of all, I will teach you how to calculate the values of non polarized capacitors which they only have number codes printed on them. The number codes on these capacitors are not their values don’t mistaken the codes with its real value. Why do I need to know how to calculate the value? Is that your question? I have stated the reason why you should above. It is very paramount for an Electrical and Electronics Engineer to have the knowledge of calculating non polarized capacitors value. Please, I recommend you learn this!
OK! Let’s start learning how to now!
How to calculate value of capacitor number code
These are the logics
 The 1st number is the 1st digit
 The 2nd number is the 2nd digit
 The 3rd number is the number of the zeros to give the capacitance in Pico Farad (pF).
For example, to read the value of the capacitor below
The 1st number is 1 which is the 1st digit, 2nd number is 0 which is the 2nd digit, and the 3rd number is 4 which means 4zeros (0000)
Therefore we write; 100000pF = 100nF = 0.1µF
What if the number on the capacitor is 102? What is its actual value?
Thus, you will solve it this way: The first digit is “1” the second digit is “0” and the third digit which is the number of zeros is “2”. Therefore; we write “10” (for the first and second digit). Placing the figure of the third digit which is the number of zeros we finally have; 1000 which is in Pico Farad (1000pF) = 1nF = 0.001µF.
Note that; some of the capacitors will have a number and a decimal point example 1.2, 2.2, 4.4, etc. Also, some will have the numbers of Tens like 15, 20, etc. When you look very carefully at the top of these capacitors, you will notice that it is shaded black. This indicates that the value is straight away in Pico Farad (pF). Thus, for the ones above; 1.2 would be 1.2pF, 2.2 means 2.2pF, 15pF, and 20pF respectively.
Conversion of capacitance
It is also important to know how to convert capacitance from one unit to another different unit. So, in general below are the prefix, symbol, and multiple by respectively of most commonly used capacitor units.
Prefix Symbol Multiply by
Pico p 10^{12} (0.000000000001)
Nano n 10^{9} (0.000000001)
Micro µ 10^{6} (0.000001)
To make things simple, 1µF = 1,000nF =1,000,000pF
Tips of converting the units to another different unit
 Pico Farad to Nano Farad: Divide by 1,000
 Pico Farad to Micro Farad: Divide by 1,000,000
 Nano Farad to Pico Farad: Multiply by 1,000
 Nano Farad to Micro Farad: Divide by 1,000
 Micro Farad to Pico Farad: Multiply by 1,000,000
 Micro Farad to Nano Farad: Multiply by 1,000
Example1
Convert 10pF to nF
From the tip N0.1, we will divide it by 1000. Thus; 10/1000= 0.01nF
Example2
Convert 22nF to µF
22/1000 = 0.022µF
Example3
What is the value of 0.15µF in pF?
0.15 X 1,000,000 = 150,000pF
With the tips above, you can convert unit capacitance to different units.
However, you might come across of some capacitors with number codes followed by an English alphabet or letter which do not mean units. Letters on the capacitor indicate its tolerance and sometimes company’s series.
