Title: Resistors value for the imp v2
Post by: thevorticist on May 21, 2021, 02:33:09 PM
Hi guys!

I'm building the imp2, but I can't find the correct value resistors. In specific these two:
392k         1         Metal / Carbon Film         1/8W
422k         1         Metal / Carbon Film         1/8W

In Tayda jumps from 390k to 430k and that also happens in Mouser. I believe if I use a 2k with the 390k, and a 390k, 10k, 22k I can get them, but there's not much room in the enclosure, so I was wondering if I could use a bigger one in order to be able to fit everything in it.

Thanks for you help!

Ok, I found them 1/4w instead of 1/8w... I guess that'll do.

Don't believe that it will matter if you will use 390k and 430k. Or 1/8W or 1/4W. Constructors only used "strict scale" order of resistors, but at real, it will work OK with those levels I wrote down. Or you can use original, if there is 1/4W type available.

Yep, remember that not everything is ideal... Metal film resistors have a fairly low tolerance of 1% + and - the value. That 390k could be a 393k. Measure and find a high one

Thank you! I'm almost done shopping xD (almost 5h)
