Each color band represents a number and the order of the
color band will represent a number value. The first 2 color bands indicate a
number. The 3rd color band indicates the multiplier or in other words the
number of zeros. The fourth band indicates the tolerance of the resistor +/-
20%, 10% or 5%.
In most cases, there are 4 color bands. However, certain
precision resistors have 5 bands or have the values written on them, refining
the tolerance value even more. There is no standard however, for the 5th band.
From one manufacturing company to another, the 5th band may indicate 2%, 1%,
1/2% or even closer, according to their own standards.
There are also some capacitors that are color coded. Click
