This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. It will also calculate the minimum and maximum values based on the tolerance ratio. This calculator supports resistors with 3, 4, 5, and 6 bands. 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.

Resistance colour 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. Use the following to calculate the resistance of a conductor. This calculator assumes the conductor is round. Related Ohms Law Calculator. 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 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.

In a four-band resistor, resistance colour code calculator, which is the most common, the first two bands also represent the first two significant digits. Tolerance is the percentage of error between the actual measured resistive value and the stated value. This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors.

.

With this resistor color code calculator, you'll quickly and easily find out the resistance of your resistor component. Just choose how many bands your resistor has — 4, 5, or 6, select the colors , and in the blink of an eye, you'll get the resistance with tolerance, range, and temperature coefficient value if you've chosen 6 band resistor color code. If you want to understand how to read resistor color code, scroll down, and you'll find their formulas and explanation. Also, we show a 10k resistor color code as well as many other informative examples. Color bands are an easy and cheap way of indicating the value of an electronic component. The printed alphanumeric codes would be too small to read on the tiniest resistors, so the color code was developed in the early s. The first question which usually arises is: how do I know from which end I should start reading my resistor color code? Fortunately, a couple of visual hints exist! In a usual case, the bands are not spaced regularly — there's a gap, and bands are somehow grouped.

In a three-band resistor, the first two bands represent the first two significant digits followed by one band for the multiplier. The fifth band represents the tolerance. Switching from 4 bands to 5 prompted very loud and obnoxious ads, then I find the thing just goes right back to 4 bands as soon as I select the first color. In the following, the meaning of each band is described for each type of resistor. The fourth band represents the multiplication factor of the resistance value. The application is an easy-to-use color code calculator for calculating the resistance of a resistor. The coding is defined in the international standard IEC This is due to the manufacturing process and it is expressed as a percentage of its preferred value. Binary Calculator. 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. Resistor A resistor is a component that is used in electrical circuits to limit the current flow. 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. To distinguish the reading direction, the tolerance band width is sometimes printed with 1.

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.

The color coding for resistors is an international standard that is defined in IEC 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. The fourth band represents the multiplier. The resistance of the resistor is determined by the colors of the bands. Since it is a four-band resistor, the first two bands violet and green will indicate the significant digits which are, according to the table above; Learn more about data safety No information available. This calculator supports resistors with 3, 4, 5, and 6 bands. 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. Temperature Coefficient Color:. There are also other possible variations, but these are some of the more common configurations. The fourth band is not always present, but when it is, represents tolerance. Then you need to multiply that value by the multiplier to get the resistance value of the resistor. The coding is defined in the international standard IEC
