From time to time I get a question about a 5 band resistor that does not enter into the 5-Band calculator we have on the Digi-Key site.
Here we have an example.
No matter if the blue or the black were the first line the bands would not enter correctly into the 5 band calculator. This resistor does work however in the 4-band calculator. Blue, Gray, Silver, Gold.
Now leaves a couple of questions that need to be answered. How do I tell if my resistor is a 4 band or a 5 band? If my 5 band is a 4 band then what is the 5th band?
One key indicator is to look for a gap in the bands. Most resistor companies will put a slightly larger gap between the multiplier and the tolerance gap then between the other bands. Here is an example from Yageo showing a 4 band resistor with a special band.
Here is a similar resistor showing a 5 band from Bourns. Though not as pronounced you can see there is a slightly larger gap between the Multiplier and the Tolerance band.
Now that you have identified that you have a 4 band resistor with a 5th band you want to know what it is calling out. This can also be a bit tricky.
Per IEC 60062:2016 the standard color code would call out Temp Coefficient.
This is not always the case. Yageo for instance uses a Black 5th band in certain series to call out non-inductance.
Trying to identify which you have can range from hard to impossible. If it is a color it is most likely a temp coefficient IEC 60062:2016. If your 5th band is black you are best to try to identify the resistor manufacturer and look at their data sheet.
Do you have a part you are trying to identify? Try thePart Identification category. For other questions feel free to post in the General Category and we will be happy to help.

Here is another example of a 5 band resistor that is Not a Five band resistor.
Let us look at part number 1135-1416-ND from Vishay.
The color bands on it are Brown, Black, Brown, Red and White. As the part number calls out it is a 100 ohm resistor at 2%. This will not include the White band.
The White band is calling out that it is the Military series ML-PRF-22684 with solderable leads
This information can be found on Vishay’s website.
