It is not available in 4-band and 5-band resistors. This band indicates the temperature coefficient of the resistor. Generally, 6-band resistor is a high precision resistor, in which its last band has 6 different color code. For example, the tolerance value of brown color is ☑%, for red color = ☒% and so on.
Each color represents a specific tolerance value. The tolerance band has 10 colors: brown, red, orange, yellow, green, blue, violet, grey, gold and silver. It means, the nominal value of the resistor is 100 Ω, but the actual measured value may range between 90 Ω to 110 Ω. For example, let us consider a 100 Ω resistor and it has a tolerance value of ☑0%. The tolerance band indicates that the actual value of the resistor may vary within the specified tolerance level. When you select 6-band in the resistor color code calculator, the tolerance band will be at the 5th band. The last band of the 4-band and 5-band resistors indicate the tolerance band. For red color, the assigned multiplier is 100.įinally, concatenate the digits(6, 8) and multiply it by 100 to get the resistor vaue.
Also, identify the value assigned for the third band. Now to find the resistor value, identify the significant digits of the first and second bands(Here it is blue = 6 and Grey = 8). In this resistor, let the first band be blue color, the second band be grey color and third band(multiplier band) is red color.

How to find the resistor value?įor better understanding, let us consider the 4-band resistor. If the multiplier band is Green color, 100000 should be multiplied with the digits in the previous bands. A value is assigned for each color, which is multiplied with the significant digits in the previous bands. The multiplier band of a resistor has 12 different color code: black, brown, red, orange, yellow, green, blue, violet, grey, white, gold and silver. Similarly, for 5-band and 6-band resistors, the fourth band is the multiplier band. Multiplierįor 4-band resistors, the third band is the multiplier band. In this, the first letter(in bold) signifies the color order BBROYGBVGW. The order of the colors(from black to white) can be easily remembered from the saying “ BB ROY of Great Britain has a Very Good Wife”. For example, red color corresponds to ‘2’, grey color represents to ‘8’ and so on. These 10 colors represent significant digits from 0 to 9, as shown in the above figure. It comprises of 10 colors: black, brown, red, orange, yellow, green, blue, violet, grey and white. Whereas, in 5-band and 6-band resistors, the first three bands correspond to the significant digits. The first and second band corresponds to the significant digits in 4-band resistors.
