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. Components and wires are coded are with colors to identify their value and function. The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only. All 5-band resistors use a colored tolerance band . The blank (20%) “band” is only used with the “4-band” code (3 colored bands + a blank. It includes also numerical codes, as for example often used for SMD resistors. The color code is given by several bands. Together they specify the resistance value, the tolerance and sometimes the reliability or failure rate. The number of bands varies from three till six. As a minimum, two bands indicate the resistance value.
Enter resistor color code and the online tool will return resistors value. Handy in the Electronics shop. Includes 1/4 and 1/2 watt resistors. The Resistor Color Code Calculator decodes and identifies a value and tolerance of 6 band wire wound resistors. More online conversion calculators at Digi-Key. 29 Apr How to read resistor color codes for electronic design.
Electronics Tutorial about Resistor Colour Codes used to identify Resistor Colour Bands also including Resistor Tolerances, E-series and Preferred Values. Tight tolerance resistors may have three bands for significant figures rather than two, or an additional band indicating temperature coefficient, in units of ppm/K. All coded components have at least two value bands and a multiplier; other bands are optional. The standard color code per. 3, 4 and 5 band (value to color code and color bands to value) resistor color code calculator.
