resistor color code chart
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. The extra third band is blue and so the 3 rd significant digit is 5.

6 Band Resistor Color Code Calculator.
. Red 2 hundreds place Orange 3 tens place Violet 7 ones place Black 1Ω. Because carbon resistors are physically small they are color-coded to identify their resistance value in ohms. Brown represents the multiplier 10.
They are usually higher precision resistors. 5 Band Resistor Color Code Calculator. Violet represents 7 and Black represents the value 0.
Beginning from the other end the first band and second band is yellow and violet which gives the 1 st and 2 nd significant digit of 4 and 7 respectively. The resistance value is displayed on the field below together with the tolerance and the temperature coefficient. Yellow corresponds to the value 4 in the color chart.
From the resistance color code chart we obtain a tolerance value of 1 for brown. To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change. Mnemonics for remembering color codes.

Skip to Main Content 800 346-6873. The use of color bands on the body of a resistor is the most common system for indicating the value of a resistor.
The third band is the multiplier with red representing a multiplier value of 2 10 2. Find the value and tolerance of a 4 band 5 band or 6 band resistor with our Resistor Color Code calculator or download our color code PDF for reference. Resistor Color Code Chart Resistors are devices that limit current flow and provide a voltage drop in electrical circuits.
Thus the value of the resistance to the corresponding color code is 47010 4700 ohms or 47-kilo ohm with the tolerance band being Grey which represents a tolerance of - 005. 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. Since it is a four-band resistor the first two bands violet and green will indicate the significant digits which are according to the table above.
Above is an example of a 5 band resistor. Mnemonics are the only way I can remember the. In the example shown here the 4 bands are green blue red and gold.
By using the color code chart one finds that green stands for 5 and blue for 6. Therefore the value of this resistor is 56 10 2 56 100 5600 Ω. In this case the band colors are red orange violet black and brown.
The gold band means that the resistor has a tolerance of 5. This tool is used to decode information for color banded axial lead resistors. We then multiply that number by the multiplier indicated with the 3 rd band yellow which has the value of.
Color-coding is standardized by the. 4 Band Resistor Color Code Calculator.
