What Is The Resistor Code Color For A Resistance Of 6
Trine Gritz
Resistors are usually very tiny, and it is challenging to print resistance values on them. So, colour bands are printed on them to represent the electrical resistance. These colour bands are known as resistor colour codes. The resistor colour code was invented in the 1920s by the Radio Manufacturers Association (RMA).

All leaded resistors with a power rating up to one watt are marked with colour bands. They are given by several bands and together they specify the resistance value, the tolerance rate and sometimes the reliability or failure rates. The number of bands present in a resistor varies from three to six. The first two bands indicate the resistance value and the third band serves as a multiplier. In this piece of article, let us discuss how to read resistor colour codes, look at an example and learn a mnemonic to remember the number sequence.
The tolerance values represent by how much the resistance can vary from its mean value in terms of percentage. A gold band represents the lowest variation, so be sure to buy these at the electronics store. The value of the given resistance is: 22 Ω 5%. The tolerance of the resistor can be calculated as follows:
This means that the 22 Ω resistor with a tolerance value of 1.1 Ω could range from the actual value as much as 23.1 Ω to as little as 20.9 Ω. It is important to note that the band next to the tolerance band represents the multiplier. All the bands to the left of this band represent the significant digits. There can be more than two such bands.
The capital letters represent the first letters of the colours and their positions the digit values. Now that we have an idea to determine the resistance value of a given resistor. Let us solve some problems related to this in the next section.
As we know, the first two colours represent the significant digits of resistance value so the given colours represent digits 2 and 5. The third band is a multiplier band. Hence, the colour red represents a multiplier factor of 102. The last band represents the tolerance level and the tolerance level of the resistor is 5%. Hence, the resistance value of the given resistor is 2500 5% Ω or 2.5 kΩ.
The following are tools to calculate the ohm value and tolerance based on resistor color codes, the total resistance of a group of resistors in parallel or in series, and the resistance of a conductor based on size and conductivity.
An electronic color code is a code that is used to specify the ratings of certain electrical components, such as the resistance in Ohms of a resistor. Electronic color codes are also used to rate capacitors, inductors, diodes, and other electronic components, but are most typically used for resistors. Only resistors are addressed by this calculator.
The color coding for resistors is an international standard that is defined in IEC 60062. The resistor color code shown in the table below involves various colors that represent significant figures, multiplier, tolerance, reliability, and temperature coefficient. Which of these the color refers to is dependent on the position of the color band on the resistor. In a typical four-band resistor, there is a spacing between the third and the fourth band to indicate how the resistor should be read (from left to right, with the lone band after the spacing being the right-most band). In the explanation below, a four-band resistor (the one specifically shown below) will be used. Other possible resistor variations will be described after.
In a typical four-band resistor, the first and second bands represent significant figures. For this example, refer to the figure above with a green, red, blue, and gold band. Using the table provided below, the green band represents the number 5, and the red band is 2.
The third, blue band, is the multiplier. Using the table, the multiplier is thus 1,000,000. This multiplier is multiplied by the significant figures determined from the previous bands, in this case 52, resulting in a value of 52,000,000 Ω, or 52 MΩ.
The fourth band is not always present, but when it is, represents tolerance. This is a percentage by which the resistor value can vary. The gold band in this example indicates a tolerance of 5%, which can be represented by the letter J. This means that the value 52 MΩ can vary by up to 5% in either direction, so the value of the resistor is 49.4 MΩ - 54.6 MΩ.
Coded components have at least three bands: two significant figure bands and a multiplier, but there are other possible variations. For example, components that are made to military specifications are typically four-band resistors that may have a fifth band that indicates the reliability of the resistor in terms of failure rate percentage per 1000 hours of service. It is also possible to have a 5th band that is the temperature coefficient, which indicates the change in resistance of the component as a function of ambient temperature in terms of ppm/K.
More commonly, there are five-band resistors that are more precise due to a third significant figure band. This shifts the position of the multiplier and tolerance band into the 4th and 5th position as compared to a typical four-band resistor.
On the most precise of resistors, a 6th band may be present. The first three bands would be the significant figure bands, the 4th the multiplier, the 5th the tolerance, and the 6th could be either reliability or temperature coefficient. There are also other possible variations, but these are some of the more common configurations.
Resistors are circuit elements that impart electrical resistance. While circuits can be highly complicated, and there are many different ways in which resistors can be arranged in a circuit, resistors in complex circuits can typically be broken down and classified as being connected in series or in parallel.
Are you having trouble reading resistor color codes? If your answer is yes, this tool is specifically designed for you! Our Resistor Color Code Calculator is a handy tool for reading carbon-composition resistors, whether it's a 4 band, 5 band, or 6 band type.
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 displayed on the field below, together with the tolerance and the temperature coefficient.
As shown above, a carbon-composition resistor can have 4 to 6 bands. A 5-band resistor is more precise than a 4-band type because of the inclusion of a third significant digit. A 6-band resistor is like a 5-band resistor but includes a temperature coefficient band (the 6th band). Below (Table 1), you can see an overview of the different band types.
The 6th band for a 6 band type resistor is the temperature coefficient. This indicates how much the actual resistance value of the resistor changes when the temperature changes. Table 5 shows these values for each corresponding color.
All 5 band resistors with the 4th band of silver or gold form an exception and are utilized on specific or older resistors. The first two bands represent the significant digits, the 3rd band is a multiplication factor, the 4th band is for tolerance, and the 5th band is for the temperature coefficient (ppm/K).
A single black band on a resistor is called a zero-ohm resistor. Basically, it is a wire link used to connect traces on a printed circuit board (PCB) that is packaged in the same physical package format as a resistor. This packaging allows the zero-ohm resistor to be placed on the circuit board using the equipment typically used to place other resistors.
When resistors are produced per military specifications, they will often include a band that indicates reliability. This band is specifically for failure rate percentage per 1000 hours of service. This band is rarely used in commercial electronics. In addition, 4 band resistors typically use this reliability band.

Color-coding is a method used to indicate the resistive value, tolerance, and temperature coefficient of resistors with low wattage rating because of their small size. Color bands are used because they can be easily and cheaply printed on a small electronic component. Color-coding is also used for capacitors, inductors and diodes.
When the resistor body surface is large enough, as in large wattage resistors, the resistance value, tolerance, and wattage are usually printed on the body of the resistor. Surface mounted resistors (SMD) use another coding system that uses alphanumeric codes printed on its surface instead of color codes.
In a three-band resistor, the first two bands represent the first two significant digits followed by one band for the multiplier. Since no tolerance band is available, the tolerance will always be 20%.
In a four-band resistor, which is the most common, the first two bands also represent the first two significant digits. The third band represents the multiplier. The fourth band represents the tolerance.
Tolerance is the percentage of error between the actual measured resistive value and the stated value. This is due to the manufacturing process and it is expressed as a percentage of its preferred value
A zero-ohm resistor is a resistor having a single black band. Its resistance is approximately zero and it is used to connect two traces on a printed circuit board (PCB). Is it used in automated PCB assembly where using the same equipment used to mount other resistors is easier than using a separate machine to install a wire jumper.
