Example for resistor color codes
The 1st and 2nd color bands indicate the value: here yellow and violet indicate 47. The 3rd color band indicates the power of 10: here red indicates 102=100. So this resistor value is 4700 = 4.7K The 4th color band indicates tolerance: here gold indicates 5%.

Capacitor Codes
If a capacitor has only a two digit number then that is the value in picofarads. If it has a three digit number then the last digit is the power of 10 multiplier. Some examples are below.
104 → 0.1μF = 100nF
103 → 0.01μF = 10nF
102 → 0.001μF = 1nF
101 → 0.0001μF = 100pF
100 → 10pF
220 → 22pF
330 → 33pF
470 → 47pF
Capacitor tolerance is designated by a letter following the number. The letters are as follows:
D 0.5%
F 1%
G 2%
H 3%
J 5%
K 10%
M 20%
Z +80/-20%
