Judging by a capacitors size and type you will quickly learn to determine if the value on the capacitor is given in pf nf or uf.
Ceramic capacitor value table.
Capacitor value table from 0 001uf to 220uf.
To prevent confusion with large numbers of zeros attached to the values of the different capacitors the common prefixes pico 10 12 nano 10 9 and micro 10 6 are widely used.
A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.
The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
Summary of common capacitor types and uses.
Marked 2a474j the capacitance is decoded as described above the two first signs is the voltage rating and can be decoded from table 2 here below.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
This prevents confusion with large numbers of zeros attached to the values of the different capacitors.
Common capacitor value for smd capacitor is almost same as ceramic and electrolytic capacitors.
Below table have all the common capacitor values listed that are useful for you.
Handy formulae for series and parallel capacitors stored charge and stored energy.
Ceramic disc capacitors have two to three digits code printed on them.
If a capacitor is f ex.
Every value shown in microfarads nanofarads picofarads european and eia mil codes and colour codes.
2a is 100vdc rating according to the eia.
Si prefixes for sub multiples.
If the capacitor code mentioned in 1 or 2 digits only then the capacitance value will be the same code value in pico farads pf.
Capacitors are available in a huge range of package styles voltage and current handling capacities dielectric types quality factors and many other parameters.
The code mentioned on the capacitor consists of 1 2 and 3 digit and all the values are in pico farads pf unit.
The main prefixes used for capacitor values are given in the table below.
The ceramic capacitor value finds by calculating the codes mentioned on it.
When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
For code 104 the two figures 10 indicate the significant figures and the 4 indicates the multiplier i e.
Then by just using numbers and letters as codes.
When converting between these it is sometimes useful to have a capacitor conversion chart or capacitor conversion table for the different capacitor values.
In view of the enormous range over which capacitor values can vary a number of different prefixes may be used.
