A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. A resistor is perhaps the most common building block used in circuits. 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.

Number of Bands:

Four Band Five Band Six Band
