This tool is used to decode information for color banded axial lead resistors. Select the number of bands, then their colors to determine the value and tolerance of the resistors or view all resistors Digi-Key has to offer. Instructions & Diagram.

Introduction. Color-coded resistor values are commonly used.Color bands are used to identify almost all leaded resistors with a power rating of up to one watt.The international standard IEC 60062 specifies the coding system. The marking codes for resistors and capacitors are specified in this standard.The standard includes numerical codes that are often used for surface mount SMD resistors, in
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.
This standard describes the marking codes for resistors and capacitors. Violet 7 red 2 gold 5 5 of 4700 235 4700 235 4935 4700 235 4465 the actual value can range from 4465 to 4935. Resistor color coding applying the color code the amount by which the actual r can differ from the color coded value is its tolerance.
2nd band color gives 2nd number. 3rd band color gives # of zeros. 4th band color gives tolerance or ± How to read it Resistors are color coded for easy reading. To determine the value of a given resistor look for the gold or silver tolerance band and hold the resistor with this band to the right. Then read the colored bands left to right. Three-band resistors don’t have a tolerance band. In the example above, the three bands are red, red, and black. If we look at the color code chart, that means we have the digits 2 and 2 for the first two bands and the multiplier 1 for the third band. Therefore, the value of the resistor is 22 x 1 = 22Ω.

This system was employed for resistors when the surface area was not sufficient to print the resistance value for the past time. Because carbon resistors are physically small they are color coded to identify their resistance value in ohms. All 5 band resistors use a colored tolerance band. 6 band resistor color code.
the resistance may vary from the value indicated by the color code. Because the resistors are mass-produced, variations in materials will affect their resistance. Tolerances are usually given as plus or minus of the nominal, or color-code value. Example: Brown Red Orange Gold 31 2 10 5% = 12 K , ±5%

Resistor Colour Code Examples Q1) Determine the resistance of the given resistor with the given colour sequence (Red, Green, Red, Gold). As we know, the first two colours represent the significant digits of resistance value so the given colours represent digits 2 and 5. The third band is a multiplier band.

Again, we check the resistor color code chart for red, violet and yellow, and the first, second and third bands give the significant digits of 2,7 and 4 respectively. The fourth band is black, giving a multiplier value of 10 0. Hence, we will get a resistance value of 274 × 10 0 = 274Ω.
