Ceramic Capacitor Values Table

2a is 100vdc rating according to the eia.

Ceramic capacitor values table.

The code mentioned on the capacitor consists of 1 2 and 3 digit and all the values are in pico farads pf unit. 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. The ceramic capacitor value finds by calculating the codes mentioned on it.

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. Standard capacitor values color codes over time a series of standard capacitor values have evolved just as with resistors and inductors. This prevents confusion with large numbers of zeros attached to the values of the different capacitors. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. 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. The main prefixes used for capacitor values are given in the table below.

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. Si prefixes for sub multiples.
