Like the SM footprints, but I'm not sure I see the point of the resistor color code chart these days (If I do spec a through hole resistor, 99% of the time it'll be a 1%).
- sas 13y agoThanks joe! Yeah, sadly through hole seems to be going away on the whole, but the color codes are still used often by some people, especially while breadboarding or prototyping. I actually referred to a prototype of the card myself while designing a board a few weeks ago:) so some people will likely find one side or the other more useful. Fortunately we've designed the card to be useful in a good variety engineering contexts!
- DanBC 13y agoNot sure I understand - Vishay[1] MRS25 resistors are 1% and use a colour code. (http://www.vishay.com/docs/28724/mrs16m25.pdf http://www.vishay.com/docs/28724/mrs16m25.pdf) They're generally pretty nice as resistors go. Do you spec better than that? [1] I used these when they were Philips, which shows how long it is since I was doing this stuff.
- fnordfnordfnord 13y agoMost SMT resistors use a number code. Also, colorblind people.
- joe_bleau 13y agoThe 1% series has an extra value band, which throws off their multiplier. Example: 1k 5% is brown black red (gold), but 1k 1% is brown black black brown (brown). We do use a few 0.1% values in some cal equipment--about $1 each!
