The 3 digit code 104 written over ceramic capacitor indicates its value.
Capacitor ceramico 473 j.
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.
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.
Mylar 333 100pf ceramic 101.
Then by just using numbers and letters as codes.
A second letter will be a temperature coefficient if its present.
The 3 digit capacitor code 473 stands for 47 nf in words.

The capacitor s first and second significant number ids and are the first and second values followed by the multiplier number code followed by the percentage tolerance letter code.

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.
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.
