For example 204 20 10 4 200000 pf.
100nf ceramic capacitor code.
472 47 10 2 4700 pf.
Smd ceramic capacitor codes.
Looking at our capacitor we will see its marked 474j this should be read as follows 47 times the value that can be found in table 1 corresponding to the 3rd number in this case 10000.
Similarly n51 indicates a 0 51nf or 510 pf capacitor etc.
The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
Often the value may be given in picofarads.
47 10000 470000 pf 470 nf 0 47 uf with the j meaning a 5 tolerance.
47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
Surface mount capacitors are often very small and do not have the space for markings.

Then by just using numbers and letters as codes.
502 52 10 2 5200 pf.
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.
Sometimes figures such as 10n will be seen and this indicates a 10nf capacitor.
Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1.
If a capacitor has 682 code first check the last no here last no is 2.
