Let’s take an example of a 5-band resistor with the colors given in the above image (brown, green, red, black and gold). ‘ e’ represents the 5 th significant digit, which is the fifth band color of resistor and this is the tolerance value of resistor. The actual resistor value could be as high as 22 + 1.1 23. The tolerance is +/-5 - 560k528k which means the resistor may be 28k lower or higher than the stated value. Until fairly recently, 10 tolerance resistors were the norm, but today, 5 (E24) resistors seem to be the most commonly used.

The actual resistor value could be as low as 22 - 1.1 20.9 6. Put the 5 and 6 together for 56 then multiply by 10K - 5610K 560k. Resistor color code examples E12 series resistors. Do the calculation to find that 5 of 22 is 1.1 5. Or the actual resistor value could be as high as 22 + 5 of 22 4. This explains why you find more resistor options in a common value such as 4. This process helps simplify inventory and purchasing needs. The values are calculated using some math magic (see: Renard Series & E series of Preferred Numbers). Product Code: EC-2042 Availability: 5067. ‘ d’ represents the 4 th significant digit, which is the fourth band color of resistor and this is the multiplier value used in formula. The actual resistor value could be as low as 22 - 5 of 22 3. Standards are set in place that help determine common resistor and capacitor values. Buy 6.8K ohm SMD Resistor - 1206 Package -1/4W - 20 Pieces Pack online at lowest price in India with best. This shows that the resistor has a value of 4.7 kilo ohms, with tolerance +/- 0.05 and with a temperature coefficient of 10 ppm/K. Here also, if we can consider the same color code used for the 5-band, with an additional temperature coefficient band with a blue color. ‘ c’ represents the 3 rd significant digit, which is the third band color of resistor. 6-Band Resistor Color Code Identification. ‘ 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 5-band resistor To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator. A resistor is identified by its pattern of color of bands.
