Title: Where to get 392k & 422k for Kingslayer / Sunking?
Post by: fman7 on May 25, 2014, 02:46:02 AM
Hey,

having trouble sourcing the 392k and 422k resistors for the Kinslayer/Sunking builds.

Can I use 390k and 430k?

thnks

Frank

Generally, within 5% is considered irrelevant because that's the tolerance of a typical carbon film resistor. Along those guidelines, those values should be fine.

Got mine from Mouser

I put two in series to get the correct value. Plus it looks funny:-)

Mouser FTW with these funky values.

Thanks for responses, will go for the series option.

Should have mentioned I'm in Australia, so Mouser etc is out of the question.

thnx

There's also the parallel option, plug in the desired resistance and the % tolerance - the software spits out every possible pair that meet your parameters.

If your hung up on the values you can always buy a bunch of 390K and 422K and measure the resistance to find a 392K and a 422K. In this case I would go with carbon film 5% tolerance resistors to make it easier. I tried to do it with 1% metal film and it took a while to find a match. Lie mentioned above, it's not really a big deal...
