Resistor Color Diagram

A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. The use of color bands on the body of a resistor is the most common system for indicating the value of a resistor.

What Is A Resistor Types Of Resistors Resistor Color Code

This standard describes the marking codes for resistors and capacitors.

Resistor color diagram. The third column assigns a number to each color. There are other mnemonics for this which well touch on later. In the case of 5 band and 6 band resistors the first three bands indicate the significant digits and the fourth band indicates the multiplier.

The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. The colors brown red green blue and violet are used as tolerance codes on 5 band resistors only. Referring to this diagram as you read will make understanding resistor color code a breeze.

Resistor color code chart. Resistor color code 1st nd digit 2 digit 3rd digit multiplier stripe tolerance 4th stripe black 0 0 0 x 1 brown 1 1 1 x 10 1 red 2 2 2 x 100 orange 3 3 3 x 1 000 yellow 4 4 4 x 10 000 green 5 5 5 x 100 000 blue 6 6 6 x 1 000 000 purple 7 7 7 grey 8 8 8 white 9 9 9 gold x 01 5 silver x 001 10 10k ohm 1 tolerance st. Standard resistor values and color components and wires are coded with colors to identify their value and function.

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. The left column of the chart starts with a helpful mnemonic for remembering the colors and their order. This chart shows you how you can read the resistor color bands.

In this type of resistor when the resistance of these resistors decreases once the temperature increases which is known as the high negative temperature coefficient. This circuit can be designed using a resistor a battery and an led. The coding is defined in the international standard iec 60062.

Try out our resistor color code calculator in our tools section. In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other uses. In the case of a 3 or 4 band resistor the first two band indicate the significant digits and the third indicates the multiplier.

Resistor color codes chart. 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.

The simple resistor circuit diagram is shown below. Resistor color code chart resistors are devices that limit current flow and provide a voltage drop in electrical circuits. Because carbon resistors are physically small they are color coded to identify their resistance value in ohms.

We know that the function of resistance is to restrict the flow of current throughout the component. Practically all leaded resistors with a power rating up to one watt are marked with color bands. More online conversion calculators at digi key.
