The total resistance is therefore: 330Ω ± 5% Ω. This example uses a gold band, giving us a tolerance of 5%. The most common values are 5% (designated by a gold band), and 10% (designated by a silver band). So the total value of the resistance given by the colors is 33 (from digits) x 10 1 (from multiplier) Ω = 330 Ω.īand # Four – Tolerance: Gives the value of the tolerance for the resistor. In this case, the third band is brown, which corresponds to the number 1. The actual multiplier is 10 n, where n is a value that corresponds to the color of the band. Therefore the digits from band one and band two are: 33.īand # Three – Multiplier: Takes the digits and multiplies them by a value given by this band. This is added to the right of the first digit (from band one). This band is also orange, corresponding to the value 3. The first band is orange, which corresponds to a value of 3.īand # Two – 2 nd Digit: The second digit of the resistance value. The Four Band 330 Ohm ResistorĮach band on the resistor has a specific role:īand # One – 1 st Digit: This is the first digit of the resistance value. Once you learn the four band system, it is very easy to understand five and six band resistor color codes. It’s easiest to learn four band resistors first. Six band resistors are exactly like five band resistors but also add a band for the temperature coefficient. Five band resistors have three bands for digits. Resistor color codes consist of digits followed by a multiplier and a tolerance value.įour band resistors have two color bands for digits.

This process is covered in greater detail below.
RESISTOR COLOR CODE FULL
Multiply the value designated by the first two bands with the multiplier to find the full value of the resistor. The first two bands give us a base value, which needs to be multiplied by the multiplier to identify the full resistance value.ģ) The third band is the multiplier. This band gives us the tolerance of the 330 Ohm resistor.Ģ) After identifying the last band, look at the bands on the opposite side of the resistor. The last band is usually gold or silver and should be separated from the other bands by a small gap. Helpful Tips for Using Resistor Color Codes (for four band resistors):ġ) Identify the last band first. Higher quality resistors have tighter tolerances. Six band resistors add another color band to the end of the resistor that tells us the temperature coefficient, or how sensitive the resistor is to temperature changes.Īll resistors have a tolerance value, which means that the value is unlikely to be exactly 330 Ohms. Note that a five band resistor’s extra band is used to determine the nominal value. In five band resistors, the first four bands tell us the nominal value of the resistor. In a four band resistor, the first three bands give us the resistor’s nominal value and the 4th band gives us the tolerance. 330 Ohm Resistor – 4, 5, 6 Band Color Code Chart Band One Band Two Band Three Band Four Band Five Band Six Four Band Orange Orange Brown ± % – – Five Band Orange Orange Black Black ± % – Six Band Orange Orange Black Black ± % R(T°) 330 Ohm Resistor Color BandsĮach band on a color-coded resistor has a specific purpose. In this article, we’ll cover in detail how to quickly identify and read 4 band, 5 band, and 6 band 330 Ohm resistors. Note that the color of the third band changes from brown to black for five and six band, 330 Ohm resistors. The 330 Ohm resistor color code allows us to quickly identify the resistance value and tolerance of a 330 ohm (330 Ω) resistor. It is a good practice to confirm the value using an ohmmeter or multimeter. However depending on the lighting and pigments used by the manufacturer of the resistor, the colors red, orange, and brown might be easily confused. In particular, a four band 330 Ohm resistor can be quickly identified by two orange bands and a brown band. Like any color coded resistors, its’ value can be quickly determined just by looking at the color bands on the body of the resistor. The 330 Ohm resistor is a common resistor in electronics.
