3 BAND RESISTOR COLOR CODE CALCULATOR CODE
The color code for tolerance is as follows:Īn example calculating the range of a resistor value is: The fifth band is the tolerance and represents the worst case variation one might expect from the nominal value. The resistance range is normal between 465.3K-474.7K. Therefore, the yellow color in the first band is 4 the purple color in the second band is 7 the black color in the third band is 0 the fourth band is 10 to the 3rd power, which is 1000 the fifth band has an error of ☑% for brown. The four colors on one side are closer, and the other color circle is farther apart, so from left to right, we know that the first color circle is yellow, followed by purple, black, orange, and brown. (2) Then we need to know which is the first color circle. We need to read according to the table of five bands. There are five colors, so it is five bands. (1) First of all, we need to know which is the first digit.
3 BAND RESISTOR COLOR CODE CALCULATOR HOW TO
The values of color bands will be like this: Green = 5, Brown = 1, Violet = 7, Black = 100, Gold = 5%, Orange = 15ppm.Īfter mastering the above table, now we will learn how to read the 5-band resistor. If the colors on a 6 band resistor is in this order: green, brown, violet, black, gold and orange. How to read a 6 band resistor color code? But 470K is a standard 5% value and is not a standard 1% value whereas 475K is a standard 1% value.ĥ. The final band of each resistor is the tolerance. What is the difference between a 4 band resistor and a 5 band resistor? Therefore, the first three bands indicate the significant digits, the fourth band is the multiplying factor and the fifth band represents the tolerance.Ĥ. Resistors with high precision have an extra band to indicate a third significant digit. What is the fifth color band on a resistor? Position the resistor with this band on the right side and again read your resistor from left to right.ģ. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. Resistors never start with a metallic band on the left. Place the tolerance band on the right and read the bands from left to right.Always read resistors from left to right. If the gold or silver band is present closer to the end, it is definitely the tolerance band.
The first band shall be closer to the end of the resistor.Here are a few tricks to identify the first band of the resistors: If we are reading the bands in the wrong direction, we end up calculating a wrong value. The color bands must be read from the right direction. Compare and verify the displayed image to your resistance.Below are a few tips to identify the first band.
Select the band’s colors and let the tool work for you. If you are not good at reading color codes, this resistor color code calculator can be helpful to you. How to use the resistor color code calculator tool?
