Ceramic Capacitor Values Table

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.

Ceramic capacitor values table.

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. Ceramic disc capacitors have two to three digits code printed on them. This prevents confusion with large numbers of zeros attached to the values of the different capacitors. Capacitors are available in a huge range of package styles voltage and current handling capacities dielectric types quality factors and many other parameters.

Standard capacitor values color codes over time a series of standard capacitor values have evolved just as with resistors and inductors. 2a is 100vdc rating according to the eia. The ceramic capacitor value finds by calculating the codes mentioned on it. The main prefixes used for capacitor values are given in the table below.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Si prefixes for sub multiples. 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. In view of the enormous range over which capacitor values can vary a number of different prefixes may be used.

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. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
