Resistor Color Code

This is the best and by far the fastest and most easy Resistor Color Code calculator.
Calculate resistor value by selecting the band colors.

Or Reverse:

Enter a resistor value and find the color code.If the value is not an standard E-series value the two nearest values are shown.


* 3, 4, 5 and 6 band resistor support *

If the resistor has a standard E-series value then also the E-series (E3, E6,E12, E24, E48, E96, E192) number will be shown.

Perfect for me! I wanted a quick check by simply selecting the colors instead of using charts or a vom for quick fixes. Obviously this is not always the best way but for me it will help in a significant amount of times. Many thanks!

I love that I am able to enter in my value and get color codes. very helpful!

Best app

This small app can work with either typing in values or selecting color bands. I prefer to type in my value. Its then shows the resistor and sets the number of bands according to the tolerance. When next higher or next lower are pressed the nearest STANDARD values are shown. Resistors are normally manufactured with STANDARD values. When you design a circuit you need to ask for a STANDARD value resistor.

Does exactly whay its supposed to do, very easy to use.

Is it possible to add camera read of resistors colour codes for people with bad eyesight?

Great application

I do not normally do reviews, so by doing this one, you know it has to be good, also liked the reverse look up feature. Very handy tool, plus quick and easy to use.

This app helped me sort out my box of over one thousand resistors. Really useful with different amounts of lines and you can convert colours into values and values into colours :)

Why does a resistor calculator need full network access and need to know about other network access? Ads. OK. Why do you need to know about other network activity? What are you capturing and where are you sending it?

Thank you for this great app!

Just what I was looking for. I have recently got into building crystal radios, this is a great tool to figure out what resistor is needed when reading a schematic.

It is ausome it realy works giving result in fraction of time......

A. G. u. Aug 3, 2012     

couldn't be simpler, and this saves so much time when I'm sorting through resistors

A. G. u. Mar 23, 2012     

Doesn't get much easier than that!

colors are off touch brown and green shows, you touch red and orange shows as well as the wrong value. Installed and uninstalled on Vizio tablet with Android 2.3 os.

Works great for me! Sprint SGS2 E4GT. Thanks!

Works like it should, thanks.

Most of these phone apps have way more info than needed, this one is quick and to the point... Good job!

A. G. u. Dec 28, 2011     

Well if you're looking for a simple easy to use resistor colour code app, look no more. fast selector and multiplier, easy to read display, no stupid bloatware or unwanted information. Thanks
