Resistor colour coding uses coloured bands to easily identify a resistors resistive value and its percentage tolerance. It is not possible to have each and every value of.

To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change.

What is resistor colour code. 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. Standard resistor values and color components and wires are coded with colors to identify their value and function.

There are many different types of resistor available which can be used in both electrical and electronic circuits to control the flow of current or to produce a voltage drop in many different ways. Try out our resistor color code calculator in our tools section. The colors brown red green blue and violet are used as tolerance codes on 5 band resistors only.

Colors are assigned to all the numbers between 0 and 9 and the color bands basically translate the numbers into a visible code. In 1930 the first radios with rma color coded resistors were built. 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.

4 band resistor color code calculator. 1 if the bands on the body of the resistor are red red orange and gold then the register value is 22 103 and its tolerance is 5 that is 22 kw 5. Select the number of bands then their colors to determine the value and tolerance of the resistors or view all resistors digi key has to offer.

So for example if a resistor has brown and red as the first two bands the most significant digits will be 1 and 2 12. There are various values of resistors available from some ohms to millions of ohms. Examples for 4 band color code.

This tool is used to decode information for color banded axial lead resistors. 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. 2 if the band on the body of the resistor is brown black brown and silver then the register value is 10101 w and its tolerance is 10 that is 100w 10.

Black is 0 brown is 1 red is 2 and so on see the color code table below. Before industry standards were established each manufacturer used their own unique system for color coding or marking their components. In the 1920s citation needed the rma resistor color code was developed by the radio manufacturers association rma as a fixed resistor coloring code marking.

4 band resistor color code calculator. 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. 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 values are often indicated with color codes.
