The online resistor calculator is a tool by Utmel Electronic used to calculate resistor values for 4 band, 5 band, and 6 band resistors, in the range of ohms, Kilo Ohms, and Mega Ohms typically. And this resistance calculator is developed to calculate the color code using the resistor color codes on their surface.Just select the right color corresponding to each column and you can get the Resistor value on the right of the calculator immediately.
Take a 4-band resistor as the example, 10k ohm resistor color code 4 band is: Brown-Black-Orange-Red. So the 1st band of Color: Brown, 2nd band: Black, Multiplier: Orange and Tolerance: Red. Thus, the output of resistor value is 10K ohms 2%. And the below picture shows you the 100 Ohm Resistor Color Code for 4-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.
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.
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.
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).
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.
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 50C results in a 1% change in value. The color chart above shows the most frequent values for this band.
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.
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.
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.
Resistors are available in many different values, shapes, and physical sizes. Practically all leaded resistors with a power rating up to one watt have a pattern of colored bands that are used to indicate resistance value, tolerance, and sometimes even the temperature coefficient. There can be anywhere from three to six colored bands on the body of a resistor, with four bands being the most common variation. The first few bands always represent digits in the value of resistance. Then you will find a multiplier band to signify moving the decimal right or left. The last bands represent tolerance and the temperature coefficient.
The first two bands always denote the first two digits of the resistance value in ohms. On a three or four-band resistor, the third band represents the multiplier. This multiplier will basically shift your decimal place around to change your value from mega ohms to milliohms and anywhere in between. The fourth color band signifies tolerance. Keep in mind that if this band is absent and you are looking at a three-band resistor, the default tolerance is 20%.
Resistors with high precision have an extra color band to indicate a third significant digit. If your resistor has five or six color bands, the third band becomes this additional digit along with bands one and two. Everything else shifts to the right, making the fourth color band the multiplier and the fifth band the tolerance. A six-band resistor is basically a five-band type with an additional ring indicating the reliability, or the temperature coefficient (ppm/K) specification. Using brown, the most common sixth band color, as an example, every temperature change of 10C changes the resistance value by 0.1%.
A resistor is identified by its pattern of color of bands. There are 4, 5 and 6 band resistors. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.
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.
Not only does the colors of the bands matter, but also the order in which the colors appear. How do we know what each color means? The first step is to orient our resistor in the correct direction. On one side of the resistor the band color will be either silver or gold. This band should be placed on the right-hand side of the resistor.
Now that our resistor is oriented correctly, we can identify the other color bands on the resistor body We have labeled the bands on this resistor in order below: The colors on each band have a particular significance.
A: Sometimes different manufacturers will use alternative body colors (blue vs tan) and it can mean that they are made of different materials. For our purposes in beginning electronics, all resistor body colors are equal.
Resistors are color coded. To read the color code of a common 4 band 1K ohm resistor with a 5% tolerance, start at the opposite side of the GOLD tolerance band and read from left to right. Write down the corresponding number from the color chart below for the 1st color band (BROWN). To the right of that number, write the corresponding number for the 2nd band (BLACK) . Now multiply that number (you should have 10) by the corresponding multiplier number of the 3rd band (RED)(100). Your answer will be 1000 or 1K. It's that easy.
