The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. It explains how to use the chart to. Learn how to read resistor color codes from resistors.
This standard describes the marking codes for resistors and capacitors. Violet 7 red 2 gold 5 5 of 4700 235 4700 235 4935 4700 235 4465 the actual value can range from 4465 to 4935. Resistor color coding applying the color code the amount by which the actual r can differ from the color coded value is its tolerance.
Tolerance is usually stated in percentages. The resistor value is read from the left to right. Also calculate the tolerance as well.
How does the resistor color code work. The coding is defined in the international standard iec 60062. Practically all leaded resistors with a power rating up to one watt are marked with color bands.
