I have found a article where capacitance calculation has been explained wellit may be useful for others.

How to find the value of capacitor. How to determine the value of capacitors with printed bodies. Capacitor value should be large enough that it can provide enough voltage2 volts means 7v for 7805 to the regulator ic means voltage across capacitor should not go below 7v. This letter represents the tolerance of the capacitor meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor.

How to read capacitance values on a capacitor. Below is a very useful chart for calculation the right value of ceramic non polarized capacitors. But in disc capacitors only a number is printed on its body so it is very difficult to determine its value in pf kpf uf n etc.

By doug lowe. Electronics all in one for dummies. First of all we boil it down to two capacitor types.

Experiments with a capacitor introduction. Calculate capacitor values this calculator is used to find the value of a capacitor from the 3 digit code printed on its side. A storage oscilloscope enables the voltagetime graph for a capacitor charging through a resistor to be displayed and from the print out a value of the time constant for the circuit to be calculated.

If theres enough room on the capacitor most manufacturers of electronics components print the capacitance directly on the capacitor along with other information such as the working voltage and perhaps the. 151k 15 x 10 150pf 10. I have also written about how to choose capacitor values that i recommend you check out.

Let us see the methods to identify the capacitor and to calculate its value. After reading this my goal is that you should be able to go and find the capacitor you need right away. For some capacitors the value is printed in terms of uf while in others a eia code is used.

Enter the code in the box below and then hit the button to calculate the value of the capacitor. Ceramic capacitors which are usually tiny pancakes with two pins typically list the tolerance value as one letter immediately after the three digit capacitance value. How to calculate the value of ceramic non polarized capacitors.

There are special codes and marking on capacitor which tell about the value of capacitor.
