Let’s take an example of a 4-band resistor with the colors given in the above image (brown, blue, red and gold). ‘ d’ represents the 4 th significant digit, which is the fourth band color of resistor and this is the tolerance value. ‘ c’ represents the 3 rd significant digit, which is the third band color of resistor and this is the multiplier value. ‘ b’ represents the 2 nd significant digit, which is the second band color of resistor. ‘ a’ represents the 1 st significant digit, which is the first band color of resistor. Just have a look to the resistor color code chart below and see the calculations, how the resistance value is calculated according to this chart.Ĭalculating resistance for a 4-band resistor To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator. The TCR is measured in ppm/☌ units.A resistor is identified by its pattern of color of bands. The final band represents the temperature coefficient of resistance (TCR), which is the change in resistance per unit resistance as the temperature changes by 1 degree C. The third band is the multiplier and the fourth band is the tolerance.įor 5-band resistors, the first three bands represent the first three significant digits of resistance, followed by the multiplier band, which is then followed by the tolerance band.įinally, for 6-band resistors, the first three bands represent the three digits of resistance, followed by the multiplier band, then followed by the tolerance band. While a fourth band, tolerance, is not available, the tolerance is always ☒0%.įor 4-band resistors, the first two bands represent the first two significant digits of resistance. In 3-band resistors, the first two bands represent the first two significant digits of the resistance value in Ohms. Gold or silver bands are always located at the right-most end as they are only used for multiplier and tolerance bands. The bands are read from left to right, with the tolerance band being often printed at a wider gap from the other bands to distinguish reading direction. Resistors are painted with three to six bands which indicate resistance, tolerance, and sometimes the temperature coefficient of resistance. This resistor color code calculator is designed to help identify and calculate values on your resistors. Many resistors have color-coded bands which identify varying resistance values and tolerances. Circuit design engineers can use resistors to control both the voltage and amperage at a particular point in a circuit. To prevent damage to sensitive components from a voltage overload, a resistor can be used in series with that component, creating a voltage drop and protecting the component from harm. A resistor is an electrical component regulating the flow of current in a circuit.
