Ceramic disc capacitors have two to three digits code printed on them.
Ceramic capacitor value table.
Common capacitor value with codes in a chart.
Handy formulae for series and parallel capacitors stored charge and stored energy.
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.
Standard capacitor values color codes over time a series of standard capacitor values have evolved just as with resistors and inductors.
Common capacitor value for smd capacitor is almost same as ceramic and electrolytic capacitors.
If a capacitor is f ex.
2a is 100vdc rating according to the eia.
For code 104 the two figures 10 indicate the significant figures and the 4 indicates the multiplier i e.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
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.
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.
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.
This prevents confusion with large numbers of zeros attached to the values of the different capacitors.
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.
Below table have all the common capacitor values listed that are useful for you.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
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.
Then by just using numbers and letters as codes.
In view of the enormous range over which capacitor values can vary a number of different prefixes may be used.
When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
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.
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.
Capacitor value table from 0 001uf to 220uf.
Every value shown in microfarads nanofarads picofarads european and eia mil codes and colour codes.
The ceramic capacitor value finds by calculating the codes mentioned on it.
