Common capacitor value with codes in a chart.
Ceramic capacitor value table.
Si prefixes for sub multiples.
Common capacitor value for smd capacitor is almost same as ceramic and electrolytic capacitors.
Capacitors are available in a huge range of package styles voltage and current handling capacities dielectric types quality factors and many other parameters.
In view of the enormous range over which capacitor values can vary a number of different prefixes may be used.
Then by just using numbers and letters as codes.
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.
The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
Ceramic disc capacitors have two to three digits code printed on them.
The main prefixes used for capacitor values are given in the table below.
Below table have all the common capacitor values listed that are useful for you.
When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
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.
The code mentioned on the capacitor consists of 1 2 and 3 digit and all the values are in pico farads pf unit.
When converting between these it is sometimes useful to have a capacitor conversion chart or capacitor conversion table for the different capacitor values.
Standard capacitor values color codes over time a series of standard capacitor values have evolved just as with resistors and inductors.
The ceramic capacitor value finds by calculating the codes mentioned on it.
Capacitor value table from 0 001uf to 220uf.
This prevents confusion with large numbers of zeros attached to the values of the different capacitors.
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.
Summary of common capacitor types and uses.
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.
If a capacitor is f ex.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
2a is 100vdc rating according to the eia.
Every value shown in microfarads nanofarads picofarads european and eia mil codes and colour codes.
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.
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.
