![]() ![]() Scramble them up again and sort them again. There’s a big world beyond.Īlthough it is somewhat limited in value with smd resistors, the *only* way to learn the resistor color code is as follows and it takes maybe 3 or 4 hours and it will last you for a lifetime:īuy an assortment of 1/8 watt resistors, maybe 300 of them and if they are all grouped together with tape, cut them apart where they are all loose. ![]() There are good reasons to check, in case the resistor is out of spec or marked wrong, but that’s different.īeginners shouldn’t stay as beginners. And if you use a DMM, you’ll never learn the code. We didn’t have DMMs back then, so checking on an analog meter took more effort than reading the color code. I don’t have a method, I look at a resistor and know. Nobody taught me, I didn’t think it out, it was just part of it all. I just memorized the color code by looking up colors on the color code chart in the ARRL Handbook. But soon I was buying “computer boards” (no ICs just transistors) and sfripping them. I guess I looked up the first resistors on a chart. I can’t remember my thought process 51 years ago. The problem is, I think these things make beginners think the process harder than it is. Radio Shack used to sell a decoder wheel. The whole mnemonic thing, to remember the color sequence is like trying to send morse code by looking up the character first. One important thing is there’s a whole industry around decoding color codes, and beginners buy into it. Posted in hardware Tagged cheat sheet, resistor, resistor color codes Post navigation It may seem like through-hole resistors have always had color bands, but that is not the case. This happens to apply nicely to resistors themselves, in fact. After all, just because something has always been so doesn’t mean there isn’t room for improvement. Is his proposed method more intuitive, or less? We think makes a pretty good case, but you be the judge. shares a prototype of a new kind of chart in his post, so if you have a few minutes, take it for a spin and see what you think. The big difference is that the user is asked to approach 560 kΩ not as 56 * 10 kΩ, but as 5.6 * 100 kΩ. He suggests that it makes more sense for a user to start with looking up the colors to make 5.6 (green-blue), then simply look up that a following yellow band means resistance in the 100 kΩ range (assuming a four-band resistor) therefore 560 kΩ is green-blue-yellow. A search for a more intuitive way is what led to his alternate cheat sheet for resistor color codes.Ĭolor code references typically have a reader think of a 560 kΩ resistor as 56 * 10 kΩ, but to, that’s not as simple as it could be. Some people look at a venerable resource like resistor color code charts and see something tried and true, but to, there’s room for improvement. ![]()
