The values of 3-band resistors have a tolerance of 20 and are commonly used by hobbyists or when the resistance value is not critical. Ask a new question Source codeĭCode retains ownership of the 'Resistors' Color Code' source code. The higher the value of a resistor, the more it resists the current flow in an electronic circuit. Color codes for fixed resistors - values and tolerances - online calculator. The TCR is measured in ppm/☌ units.The role of a resistance is to withstand/resist the passage of the current. 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. To determine the value of a given resistor look for the gold or silver tolerance band and hold the resistor with this band to.

#RESISTOR COLOR CODE HOW TO#

How to read it Resistors are color coded for easy reading. 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. Resistor Color Code 1st band color gives 1st number 2nd band color gives 2nd number 3rd band color gives of zeros 4th band color gives tolerance or ±. 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. a represents the 1st significant digit, which is the first band color of resistor. Many resistors have color-coded bands which identify varying resistance values and tolerances. Calculating resistance for a 5-band resistor. Circuit design engineers can use resistors to control both the voltage and amperage at a particular point in a circuit.

#RESISTOR COLOR CODE SERIES#

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. Resistor Color Code Band 1 Band 2 Band 3.22 ohm R22 Red Red Silver.27 ohm R27 Red Purple Silver.33 ohm R33 Orange Orange Silver.39 ohm R39 Orange White Silver. If the resistance code seems doubtful, measure the resistance with the help of an ohmmeter.

Check the manufacturers documentation guide and make sure about the colour-coding system used. If you work with electronics for a bit, you will find yourself searching online for terms like resistor color code because the colorful little stripes. A resistor is an electrical component regulating the flow of current in a circuit. A resistor has many colour bands, where each band carries a specific purpose and function.
