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.
Capacitor ceramico 473 j.
Coc473 50v capacitor ceramico 473 50v 473 47000pf 473 47nf 50v 473 0 047uf 50v.
Then by just using numbers and letters as codes.
Mylar 333 100pf ceramic 101.
A second letter will be a temperature coefficient if its present.

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
Capacitor 473 47 nf capacitor 683 68 nf capacitor 104 100 nf capacitor 154 150 nf capacitor 224 220 nf capacitor 334 330 nf capacitor 474 470 nf capacitor 684 680 nf.
47 10000 470000 pf 470 nf 0 47 uf with the j meaning a 5 tolerance.
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.
Most capacitors actually have the numeric values stamped on them however some are color coded and some have alphanumeric codes.
The 3 digit code 104 written over ceramic capacitor indicates its value.
This is a simple online calculator for color band resistor marking inductor color band marking ceramic or tantalum capacitor 3 digit marking and smd resistor 3 digit 4 digit 10 5 2 and eia 96 e96 1 tolerance code marking.
The first two digits 10 of this code are first two digits of capacitor value and third digit 4 gives the number of zeroes to be added so as to get capacitor value in pico.
