The application supports color codes for 3, 4, 5, and 6-band resistors. Resistor A resistor is a component that is used in electrical circuits to limit the current flow.

Resistance colour code calculator

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. 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. The coding is defined in the international standard IEC It describes the coding standard for both resistors and capacitors.

The third band represents the multiplication factor of the resistance value. Its resistance is approximately zero and it is used to connect two traces on a printed circuit board PCB.

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. The larger gap occurs before the tolerance band.

The coding is defined in the international standard IEC This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. 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. When a current I of one Ampere passes through a resistor with a voltage drop U of one Volt, the resistance of a resistor R corresponds with one Ohm.

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; The first band represents the first digit of the resistance value. For this example, refer to the figure above with a green, red, blue, and gold band. Resistors cases usually have three to six bands that indicate their resistance, tolerance and sometimes their temperature coefficient of resistance TCR. The sixth band represents the temperature coefficient of the resistance value.

The fourth band represents the multiplier. This calculator assumes the conductor is round. The fourth band is not always present, but when it is, represents tolerance. Contains ads In-app purchases. Color-coding is also used for capacitors, inductors and diodes. Using the table, the multiplier is thus 1,, To calculate the resistance value, you need to group the values of the significant digits bands — i. 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. It will also calculate the minimum and maximum values based on the tolerance ratio. Related Ohms Law Calculator. Resistors are circuit elements that impart electrical resistance. Using the table provided below, the green band represents the number 5, and the red band is 2. Only resistors are addressed by this calculator. 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. For this example, refer to the figure above with a green, red, blue, and gold band.
