How To Calculate Resistor Value Using Color Code

Capacitor Colour Codes And Colour Code Descriptions

Resistors come in variations with 4 5 or more color bands where a 4 band color code is most common.

Colour coding of resistors calculator. The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. More online conversion calculators at digi key. Back to conversion calculators.

Explanation formulas and charts are added below each resistor color code calculator. How to calculate the resistance. Color bands are used because they can be easily and cheaply printed on a small electronic component.

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. Skip to main content 800 346 6873. Jrcalc is a free resistor color code calculator which is intended to do both color code to value and value to color code calculations for resistors.

In both of these calculations the color code scheme is applicable for 4 5 and 6 band resistors. Below are given calculators for different types of resistors such as 3 band 4 band 5 band and 6 band resistors. 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.

Color coding is also used for capacitors inductors. Contact mouser usa 800 346 6873 feedback. It can be used for 3 4 5 and 6 band resistors.

For very small electronic components a color code instead of printed text is used to indicate the value rating or and tolerance. This resistor color code calculator will help you determine the value of axial resistors marked with color bands. To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change.

If your answer is yes then this tool is specifically designed for you. The resistor will visually show your band color choices and display the value of the resistor above. 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.

What are resistor color codes used for. 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. 9 different color bands are provided to add tolerance to the resistor.

Just have a look to the resistor color code chart below and see the calculations how the resistance value is calculated according to this chart. To calculate the resistance of a resistor you can select the appropriate color bands in the above resistor color code calculator. Download 85 x 11 pdf.

There are 4 5 and 6 band resistors.
