How to read the color code
First find the tolerance band, it will typically be gold ( 5%) and
sometimes silver (10%)
Starting from the other end, identify the first band:
Write down the number associated with that color
In this example it is blue or 6
Now 'read' the next color:
In the example it is red so write down a '2' next to the six. (you
should have '62' so far.)
Now read the third or 'multiplier' band:
Write down that number of zeros
In this example it is two so we get '6200' or '6,200'
If the 'multiplier' band is Black (for zero) don't write any zeros down
If the 'multiplier' band is Gold move the decimal point one to the left
If the resistor has one more band past the tolerance band it is a
Read the number as the '% Failure rate per 1000 hour'
This is rated assuming full wattage being applied to the resistors.
To get better failure rates, resistors are typically specified to have
twice the needed wattage dissipation that the circuit produces) 1%
resistors have three bands to read digits to the left of the multiplier
They have a different temperature coefficient in order to provide the
