The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads.

Ceramic capacitor code values. Hence the value of the capacitor above is 47000 pf 5. These calculators can convert the 3 digit value codes and alphabetical tolerance codes found on some capacitors into the corresponding value and vice versa. Details of capacitor markings can be found in the technical data section.

For example if a ceramic capacitor has a code 5 and other has 47 their respective capacitance values are 5 pf and 47 pf. There are a number of subtle differences in the capacitor codes and markings used for different types of leaded capacitors. Engineers usually do not require calculators because the code is so simple.

The first two numbers describe the value of the capacitor and the third number is the number. Work out the capacitance units from context. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board.

Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or uf equal to 10 6 farads. Both parts of each calculator work separately you do not have to enter both value code and tolerance code. 47pf 1000 3 zeros 47000 pf.

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to. On a larger capacitors there is sufficient space to mark the value the tolerance working voltage and often other data such as the ripple voltage.

The capacitors first and second significant number ids and are the first and second values followed by the multiplier number code followed by the percentage tolerance letter code. Usually the first two digits of the code represent the significant part of the value while the third digit called the multiplier corresponds to the number of zeros to be added to the first two digits. Ceramic capacitors encoding consists 1 3 digits.

If you are new to capacitor codes then the best way to start is with a chart because that way you can see the arrangement of the code. When the first two numbers are multiplied with the multiplier. If the capacitor code consist only 1 or 2 digits it is simply their capacitance value in picofarads pf.
