![]() ![]() 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. The TCR is measured in ppm/☌ units.Resistors use the BS1852 (British standard) coding standard for value representation. 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. ![]()
