Why doesnt small bear sell 1/4w 1% metal films?

[Alpha579]

lo all,
The only reason i havent ordered from steve is he doesnt seem to sell 1/4w 1% metal film resistors...its a shame, coz his prices are great, and shipping is so much cheaper than mouser...

I don't believe 1/4W metal films are exactly necessary. I don't know why he doesn't carry any, of them, but for me, I find the ones he has to be fine.

Cheers,

hmm, i guess, but im sure i can hear a difference in noise level, and i HATE noise!

[Paul Perry (Frostwave)]

I don't believe there is a noise difference between a 1% metal film and a 5% metal film.

[Alpha579]

hmm, does he stock 5% metal films...i thought they were carbon comps...andway, im under the impression that (theoretically) the lower the tolerance, the lower the noise...or that could be wrong... :?

[Peter Snowberg]

The tolerance just tells how close the actual value will be to the stated value but it have no connection with thermal noise. That's wrapped up in the technology.

ahhh, my mistake, thanx for clearing that up peter...

Check out the faq at Aiken Amps' tech page for the lowdown on resistor composition and noise.

hth,

WOW thanks Ben, some prime articles there!!! not just resistors. Good one!

[Alpha579]

yeh, thats a fantastic site

Glad I could help.  Actually, I should have posted the full URL, but I was in a rush to get out of the office on Friday.  So, for those who haven't found it yet, amidst all the other great stuff:

BTW, Randy Aiken is a great guy, very helpful with amp stuff, and his amp have a great reputation.
