If you want to find out the color bands for a value. In the case of resistors color coding is used to identify a specific resistance value for example a 100 ohms resistor or a 1 kilo ohms resistor with 5 tolerance. Resistor color code information the resistor color code is a long standing standard in both the electronics and electrical industries indicating the value of resistance of a resistor. Because resistors are not the exact value as indicated by the color bands manufactures have included a tolorance color band to indicate the accuracy of the resistor. If so please click here or click hereeach color band represents a number and the order of the. The resistor color code calculator identifies the value and tolerance of a color coded resistor given its bands colors.
Color bands are used to specify each band. This resistor color code calculator will help you determine the value of axial resistors marked with color bands. The resistor will visually show your band color choices and display the value of the resistor above. Color banded axial lead resistors with 4 or 5 bands are supported. 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 values. It can be used for 3 4 5 and 6 band resistors.
Supports resistors with 3 4 5 and 6 bands. The chart below shows how to determine the resistance and tolerance for resistors. There are three bands and sometimes four. You can select the colors of the corresponding bands by clicking on them in the table. The fourth band is the tolerance gold or silver if there is no band the tolerance is 20. The tolerance band is usually gold or silver but some may have none. The table can also be used to specify the color of the bands when the values are known.
There is a special scenario in case of 5 band resistor color code resistor where the forth strip is gold or silverin this case the first two bands shows the fist two significant digits third one is for multiplier 4th one is for tolerance and 5th one is for temperature coefficient same is in six band resistor color code resistor. Resistance is measured in ohms and there is a foundation for it called ohms law.
Color coding is used in electronics to identify between different components. 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.Ĭalculator 100 ohm resistor color code.
