How to read the code
First find the tolerance band, it will typically be gold ( 5%) and sometimes
Starting from the other end, identify the first band - write down the
number associated with that color; in this case Blue is 6.
Now 'read' the next color, here 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 and write down that number of
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 'multiplier' band is Silver move the decimal point two places
to the left. If the resistor has one more band past the tolerance band
it is a quality band.
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 1% tolerance.
