This tool is used to decode information for color banded axial lead resistors. 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. Learn more about resistors and resistor color codes. To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change. The resistance value is. For very small electronic components, a color code is used instead of printed text. This color code indicates the value, rating and tolerance. Hold the resistor with the gold or silver band to the right and read the color codes from the left to the right.
Resistor Color Code Calculator decodes value and tolerance of 4 and 5 band resistors. A resistor opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. Values are given in 'Ohms'. Resistor Calculator is an App to help the user find the value of a resistor.
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. This simple calculator will help you determine the value of any SMD resistor. To get started, input the 3 or 4 digit code and hit the "Calculate" button or Enter. This resistor color code calculator will help you determine the value of axial resistors marked with color bands. It can be used for 3, 4, 5 and 6 band resistors. This calculator will select the closest standard resistor value, from 1% 5% or 10% standard EIA values, calculates the error, and prints out a table of the standard.
