Resistor Color Codes 1

Color bands are used because they can be easily and cheaply printed on a small electronic component.

Resistor ohm to color code. The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. These resistors have two bands for the resistance value one multiplier and one tolerance band. To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change.

More online conversion calculators at digi key. Our resistor color code calculator is a handy tool for reading carbon composition resistors whether its a 4 band 5 band or 6 band type. There are various values of resistors available from some ohms to millions of ohms.

In the example on the left these bands are green blue red and gold. Resistor color code calculator the calculator above will display the value the tolerance and performs a simple check to verify if the calculated resistance matches one of the eia standard values. Resistor color coding color coding is a method used to indicate the resistive value tolerance and temperature coefficient of resistors with low wattage rating because of their small size.

By using the color code chart one finds that green stands for 5 and blue for 6. Resistor colour code standard resistor values ohms law resistors in parallel resistors in series delta y transformation calculator. If your answer is yes then this tool is specifically designed for you.

4 band colour code system. 4 band 100 ohm resistor color code is calculated as. Brown black brown gold.

1st band brown 1 1st digit 2nd band black 0 2nd digit 3rd band brown 1 multiplier 101 10. The value is thus 56100 5600 w. 4th band gold 5 tolerance thus 10015 100 ohms 100 w the tolerance will be 5 of 100 5 w theoretically the value of 100 w resistor is between 95 w to 105 w.

Resistor color code indicates that a series of colored bands are painted on the resistor and most of the manufacturers identify their resistance value by means of a color code. Select the first 3 or 4 bands for 20 10 or 5 resistors and all 5 bands for precision 2 or less 5 band resistors. Resistor colour code standard resistor values ohms law resistors in parallel resistors in series.

The four band color code is the most common variation.
