Introduction of Resistor

Resistors are usually used in electrical components with the aim of restricting the flow of electric current. They are usually tiny components with wire leads protruding from all sides. Resistors are special electronic components in circuits. It is made with the purpose of a precise quantity of electrical resistance.

The range of resistors may be from less than 1 Ohm (Ω) to over 20 mega Ohms (Ω) or 20 million Ohms (Ω). And there are two types of resistors: variable resistors and fixed resistors. A variable resistor can provide different values of resistance, however, the fixed resistor just has a single value. Meanwhile, there are 4 main classes of fixed resistors: carbon-composition resistors, Film resistors, wire wound resistors, and surface-mount resistors.

Resistor Color Bands

How to Read a Resistor Color Code Chart for 3/4/5/6 Band Resistors

Generally, the carbon-composition resistors have 3 to 6 resistor color bands. And the below electrical color code resistor chart shows you the resistor strips of the 3 band type, 4 band type, 5 and 6 band type. Compared with a 4-band resistor, a 5-band type is more precise because of its third significant digit. And a 6-band resistor has the 6th band, which is a temperature coefficient band.

From the following Resistor color code chart Calculator, we know that each color for resistor represents a number if it's found on 6-band and 5-band type from 1st to 3rd band or a 4-band resistor from the 1st to 2nd. And it is a multiplier if it is located on the 4th band of 5-band and 6-band type or the 3rd band of a 4-band resistor. You can get the tolerance values of a resistor on the 4th band for the 4-band type according to the 4 band resistor color code chart and the 5th for the 5-band and 6-band type through the below resistor color chart 5 band and 6 band. A 6-band type resistor has the 6th band, which shows you the temperature coefficient. And this value indicates how much the actual resistance value of this 6-band resistor changes when the temperature changes.

How To Read Resistor Color Code?

The easiest way to identify a resistor Color code is to know which colors represent the most significant digits. The following steps will guide you in reading a resistor color code.
1) Look for the colored bands on the resistor's body.
2) Determine which of these colors have a leading role in representing numbers.
3) Identify the numbers represented by these colors and their position.
4) Read off each of these digits from left to right on the band where it's located.

What is the purpose of resistor color codes?

Instead of written text, a color code is used to indicate the value, rating, or tolerance for very small electronic components.

Resistors are available in four, five, or more color bands, with a four-band color code being the most common. The first and second bands represent the first and second significant digits of the ohm value, respectively, while the third band represents the decimal multiplier. After that, there's a slight gap to help you distinguish between the component's left and right sides, followed by the fourth band, which indicates the resistor's tolerance.

Resistor Color Code Explained

4 band Resistor Color Code

IEC 60062 defines the color coding for resistors as an international standard. Different colors reflect significant figures, multiplier, resistance, reliability, and temperature coefficient in the resistor color code shown in the table below. The location of the color band on the resistor determines which of these the color refers to. There is a spacing between the third and fourth bands in a standard four-band resistor to show how the resistor should be read (from left to right, with the lone band after the spacing being the right-most band).

4-band resistor color code chart


Significant figure component:

four-band resistor.png

four-band resistor

The first and second bands in a standard four-band resistor reflect significant figures. Refer to the figure above with the green, red, blue, and gold bands for this illustration. The green band represents the number 5 in the table below, while the red band represents the number 2.


Multiplier:

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 multiplier is the third, blue band. The multiplier is therefore 1,000,000 when using the table. This multiplier is multiplied by the significant figures calculated from the previous bands, in this case, 52, for a value of 52,000,000 Ω (or 52 MΩ).


Tolerance:

The fourth band isn't always visible, but when it is, it stands for tolerance. The resistor value can be varied by this percentage. In this case, the gold band shows a tolerance of 5%, which is indicated by the letter J. As a result, the value 52 MΩ will differ by up to 5% in either direction, resulting in a resistor value of 49.4 MΩ - 54.6 MΩ.

Resistor Color Code 5 Band

The 5 band code is used to produce precise and high-quality resistors with tolerances of 1%, 2%, or less. The regulations are the same as in the previous system, with the exception of the number of digit bands. The first three bands will represent the value, the fourth will be the multiplier, and the fifth will be the tolerance.


Band (optional)  

A few resistors include an extra band that indicates either the dependability or the temperature coefficient, which might be confusing for novices.

The failure rate per 1000 hours is specified by the reliability band (assuming that a full wattage being applied to the resistor). This stripe is most commonly found on 4-band resistors designed for military purposes and is rarely seen in consumer circuits.

Temperature coefficients are becoming more frequent, particularly on high-quality 5-band resistors, as they become an essential element in precision components. For a resistor with a temperature coefficient of 200 ppm, a temperature change of 50°C results in a 1% change in value. The color chart above shows the most frequent values for this band.

Five band Resistor Color Code Examples:

5-band-resistor-color-code.png

5-band resistor has colors: Black-Brown-Black-Red-Brown.
The values as, 0/1//0/102 = 10 * 100 = 1K ohm/1K, with a tolerance is ±1% for Brown. Therefore, the resistor value is 900Ω to 1.01KΩ

More examples of 5-band resistance color code:

A resistor colored Blue-Brown-White-Brown-Red
The values as, 6/1//9/10 = 619 x 10 = 6190 ohms (6.19K ohms). The tolerance is ±2% for Red. Thus, the resistor value is 6.07KΩ-6.31KΩ

6 Band Resistor Color Code

For high precision, Resistors with 6 bands usually have 6 band color codes. And mostly, the 6th band is colored with brown, which means that the resistance value can change 1000 ppm = 0.1%, for a temperature change of 10 ˚C. For example, a 6 band resistor colored Orange-Red-Brown-Brown-Green-Red would be 3.21 kΩ with a tolerance of ±1% and a 50 ppm/°C temperature coefficient.

Standard EIA Decade Resistor Values

The values of resistors are divided into a number of distinct series of recommended or standard resistor values.

The varied values can be spaced in such a way that they relate to the component tolerance or accuracy since the standard resistor values have a logarithmically based sequence.

Tolerances for resistors are typically 20%, 10%, 5%, 2%, and 1% respectively. For some resistors, more precise tolerances are possible, although they are not as readily accessible and cost more.

Electronic components from a range of manufacturers may be used thanks to these standard resistor values, making sourcing considerably easier and lowering component costs.

The varied values throughout each decade can be described in a tabular form using the EIA recommended values or standard resistor values.

Despite the fact that current resistor technology allows for extremely tight tolerance levels, there is still a significant benefit to employing resistors from the E3 series. It streamlines the purchasing and production procedures by reducing the number of various types of resistors used in a design. Typically, designs strive to stick to the E3 or E6 standard resistor values, only employing the E12, E24, E48, or E96 if absolutely necessary.

Digital design, where a pull up or pull down resistor is required, is one example where values can be maintained inside the E3 series. The precise value is unimportant; just a value within the approximate range is required. The value of these resistors can be chosen from the E3 series.

Although a little more freedom is required for analogue designs, common resistor values such as E6 or E12 may be employed without issue in most electronic circuit designs. For high precision and close tolerance requirements, E24, E48, E96, or even E192 series values may be required on occasion: filters, oscillators, measurement applications, and so on.

E3 STANDARD RESISTOR SERIES

Because the E3 series resistors are the most regularly utilized, they are the most often used resistor values in the electronics sector. They're especially beneficial for resistor settings that aren't crucial in any manner. The number of distinct components in any electronic circuit design may be minimized by sticking to this series, which can assist lower manufacturing costs by decreasing inventory and the additional administration and setup necessary for additional component types in a design.

E6 STANDARD RESISTOR SERIES

In the industry, the E6 series resistor values are also commonly utilized. They provide you a greater choice of resistor values to choose from.

E12 STANDARD RESISTOR SERIES

Each subsequent resistor in the E12 series is within ten percent of the prior value. Until recently, 10% tolerance resistors were the standard, but 5 percent (E24) resistors appear to be the most used nowadays. Although they may still be found in ancient radios and amplifiers, the cost of a 5% resistor is low enough to make it the standard component in all modern electronic circuits.

Special, more expensive low-tolerance resistors with tolerance values of 2%, 1%, or less are utilized in precision applications.

E24 STANDARD RESISTOR SERIES

The following is a comprehensive list of all E24 series resistors, including shorthand notation, tolerance range, and color coding, ranging from 0.1 ohm to 10 M ohms.

For the E24 series, the fourth band is usually gold (5 percent tolerance). A fifth band may be present, representing the temperature coefficient or dependability. See also the theory behind resistor color coding and the resistor color to value and value to color code calculators for 3, 4, and 5 bands resistors.

E48 STANDARD RESISTOR SERIES

The following is a comprehensive list of all E48 series resistors, including shorthand notation, tolerance range, and color code, ranging from 0.10 ohm to 10.0 M ohms.

For the E48 series, the fifth band is always red (2 percent tolerance). A sixth band may be present, showing the temperature coefficient or dependability. See also the logic behind conventional resistor color coding and the resistor color code calculator for 3, 4, and 5 bands.

4.What does a 1k resistor look like?

1k ohm resistor color code are - Brown - black - red  
1 k ohm Resistors with 5 band are 1% tolerance resistors. First three bands determine the value of the resistor.

5.What is resistor value?

A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its 'resistance'.

6.How is a 3.9 K resistor color code?

3.9K Ohm 0.5W Metal Film Resistor (MFR) with ±1% Tolerance. 3.9K Ohm Resistor Color Code: Orange, White, Black, Brown, Brown.

7.What is a 100K resistor?

Actual value of 100k Ohm resistor is calculated as:  1st band= Brown= 1 (1st digit) 2nd band= Black= 0 (2nd digit) 3rd band= Yellow= 4(multiplier)= 10000. 4th band= Gold= ±5% (tolerance) Therefore, 10×1000000±5% ==> 1000000Ω ==> 100KΩ

8.What is resistor explain?

A passive electrical component with two terminals that are used for either limiting or regulating the flow of electric current in electrical circuits. The main purpose of the resistor is to reduce the current flow and to lower the voltage in any particular portion of the circuit.

9. What is 2.2k ohm Resistor color code for 4-band?

The color code of 2.2 k resistor is Red-Red-Red-Gold. From the above resistor color code table, you will find that Red stands for 2 and Red for 2. The third band is Red, so it means a multiplier value of 2 (100). And the 4th band is Gold, which means the tolerance is 5%. Thus the value of 2k2 resistor is 56 · 102 = 56 · 100 = 5600 Ω. Thus The resistance value lies therefore between 5320 and 5880 Ω (5560 ± 5%).

10.How do I know if I have a 10k ohm resistor?

You could read its band color and get it with the online color code calculator. For example, the 4 band 10k resistor color code is brown-black-orange-silver/gold. And the tolerance of the silver band is 10% or gold for 5% tolerance. And if it is a 5 band resistor, the 10k resistor color code will be brown-black-black-red. Meanwhile the tolerance band is separated from the other 4 bands color code. Its color could be one of several depending on the resistors tolerance.

11.How can I calculate a 6-band resistor value?

Fill in the blanks using the first five colors. Resistors with six bands are essentially five-band resistors with an extra ring showing the temperature coefficient or dependability.

12. I have a resistor with only 3 bands, How to know its value?

3-band resistors have a tolerance of 20% and are widely employed by amateurs or in situations where the resistance value is not crucial. Brown, black, and gold are the colors for a 3 band 1R0 (1 ) resistor. Between 1.2 and 0.8 will be the resistance value. 
Therefore, you don't need to enter the 4th band while using our online resistor color code calculator. Because there is not a tolerance ring for 20% resistors. However, the 3 band resistor will be calculated through the 4 bands color code rule (digit, digit, multiplier).Therefore, the 4 band resitor color code calculator is 3 band resistor color code calculator too.

For example:
3 band resistor color code of a 10K resistor with 20% tolerance is Brown, black, orange.
Resistor color code 3 band for 220 ohm resistors with 20% tolerance is Red, red, brown.

13. Which is the first band for the colored-resistors?

There are a few guidelines to follow: 
1.) The color bands on certain resistors are packed together and/or near to one end. Hold the resistor to the left of the tightly clustered bars and read the resistor from left to right. 
2.) The process for reading 5% and 10% resistors is straightforward: hold the resistor with the silver or gold band to the right and read the resistance from left to right. 
3.) The first band can't be silver or gold, so if you have one, you'll know where to start right away. As fundamental resistor values vary from 0.1 Ohm to 10 Mohms, the third color for 4-band resistors will be blue (106) or less, while the fourth color for 5-band resistors will be green (105) or less.

14. How do you read a 3-band resistor?

For a 3-band resistor color codes, the first two bands always denote the first two digits of the resistance value while the third band represents the multiplier. In the example we have, the bands are brown, black and brown. The first band is the brown band closest to the edge.
