Here is one of the most
complete component color code charts that I have seen. It covers resistors, capacitors,
and inductors for EIA, JAN, and commercial standards. If you are reading this, you
have almost certainly memorized the color / number correlation (BBROYGBVGW = 0123456789,
respectively) and know how to read a regular carbon resistor's code for resistance
and maybe even tolerance. However, if you encounter a capacitor with an array of
colored dots or a component with 5 colored bands, are you sure how to read it? This
handy-dandy chart will help. Or, you probably have an app on your phone that will
do the same thing. In 1972 when the chart appeared in Popular Electronics
magazine, nobody had ever conceived of a phone app.
