The standard decade resistors (also known as preferred values) are shown in the below table. For each tolerance band, the EIA allocates E-series (E3, E6, E12, E24 and E96) to name the resistor values. This marking code changes from one decade to another decade. So, the resistance becomes 119.7Ω -120.3Ω Standard Resistor ValuesĮlectronic color coding is standardized by the Electronic Industries Association (EIA) and later by the Radio Manufacturers Association (RMA) as standard color marking for resistors. The tolerance is ☐.25% for Blue and the temperature coefficient of resistance is 100ppm. To explore more, let’s discuss a few examples of resistor color code for 4, 5, and 6 band resistors.įor example, 4-band resistor has color Brown Black Orange Gold. This will display the true resistance value with tolerance and temperature coefficient of resistance. Normally, for gold, it is 5% and for silver, it is 10%. The tolerance value tells the accuracy at which the resistor is manufactured. You must select the right color corresponding to each column. The resistance calculator has 1 to 6 band colors with Multiplier (Mul) and tolerance (Tol) and PPM/Kelvin. The resistor calculator tool calculates the color code for 3band, 4 band, 5 band, and 6 band resistors typically in the range of ohms, Kilo Ohms, and Mega Ohms.

How to Use the Resistor Color Code Calculator Hence, they are replaced with grey and yellow color bands. The gold and silver bands are prone to misconceptions of true colors in a resistor. It is used as an interconnection between two joints.
This resistor comes with a single black band used to connect the traces on a Printed Circuit Board (PCB). Typically, a 4-band resistor comes with a reliability band. This band is not found in commercial electronics. To meet the military specification resistors often manufactured with reliability band. Now place the first two bands as the numeric value and third band as a multiplier (10 5). For example, to calculate 1.2MΩ, the resistor shows Brown Red Green colors (read from left side to right). To understand how to read the resistor color code for 3 /4/5/6 band resistors you can use this color chart.įrom the above chart, each color band on the resistor represents a number. Resistor Color Code Chart – 3 band 4 band 5 band and 6 band The variation of resistance is constant to temperature.
The higher ppm value indicates that a resistor can withstand the higher or lower temperature. The 6-band resistor has a special property of temperature coefficient of resistance represented in ppm/Kelvin. In addition to this the 4 band, 5 band, and 6 band resistors have tolerance value ranging from ☐.10 to ☑0. The multiplier value is multiplied with the significant digit number (one, two, or three digits) to get the desired resistance value. For 5 band and 6 band resistors, the first 3 digits indicate significant numbers. This number can be used as the first significant digit and second significant digit for 3 band and 4 band. To know, how to find color code, each color indicates a number starting from 0 to 9. The color code chart shows the 3 bands, 4 band, 5 band, and 6 band resistor strips. Whereas, the 4 band, 5 band, and 6 band resistors have an extra band known as tolerance. The three bands can be selected to know the resistor value. The 3-band resistor has three colors with multiplier and no tolerance. The Carbon composition resistors have 3 to 6 resistor color bands. For example, a 4.7K ohm resistor is shown as 4K7. It uses letter 'R' for ohms, 'K' for Kilo ohms, and 'M' for Megaohms. Resistors use the BS1852 (British standard) coding standard for value representation.
