01 What are Resistor Color Codes?

Electronic color code – Wikipedia

A resistor is a passive electrical component. Due to their size, they could not be printed with numbers in the past. In order to identify their values nevertheless, ring-shaped color coding has proven successful.

For today’s even smaller but flat SMD resistors, the characteristic values are applied by printing or laser engraving. These imprints are known as EIA-96 coding. Here two digits are given as code for the value and one letter as multiplier.
