I'm going to make a few impedance adapters. Who makes the smallest resistors. I'm thinking of using 1/4 watt metal film. thankws

[koike]

use the 1/8w metal films they are one of the smallest.
any brand will do.
to name a few EG. xircon or panasonic.

 

[error401]

Vishay/Dale makes some pretty blue ones, the CMF50 series

The smallest ones I've seen are the Panasonics.

 

[luvdunhill]

Phoenix or Panasonic miniature resistors from Digikey are the smallest I've found. I prefer the Phoenix personally.

WILL any brand do? since they're in the signal path, i'd think you would want resistors that offer the best possible performance.

 

[Logistics]

If they are in the signal path, doesn't he want low tolerance, non-inductive resistors?

Surface mount!

0805 can be airwired with a sufficiently steady hand.

Try some kiwame resistors.

The come as low as 2 watt I think but they are small for 2 watts.

Low noise, and carbon film- without the drift.

They might not be super small, but they will show you great improvement over metal film.

Nice Mini3 I have the same Vishay/Dale in mine , sound nice don't they ? and yes they are a bit large I guess.

Thanks for the replies. I'm gonna try a few different ones. the kiwame resistors sound interesting. Am I really going to notice a difference in the sound? Would the Ohmite carbon composite available at Digikey be as good as the kiwame? Thanks

James

BTW what kind of 3.5 jacks are those on the mini3?

ummm... do you realize how huge the kiwame's are?

I've heard that the Mills MRA-5 non-inductive wirewounds sound very good... never tried them myself however. They are rated at 5W, but are pretty small and seem to fit where a Dale RN60 would.

Try this one RC55y series from the WELWYN (TT) company.I am currently using in all of my amps.Ultra low noise and very accurate.
Series:RC55Y; Tolerance, resistance ±:±0.1%; Power rating:0.25W; Temperature, operating range:-55°C to +155°C; Resistor element type
15PPM while the dale one is 100ppm.
I think it would be quite ideal for the choice.

yeah, the Mills are a bit bigger than a RN60 ... but, in an impedance adapter?

I'd think you'd want a smaller (i.e. SMD) package... however, if you're interested in larger resistors, I'd also recommend looking at IRC GS3 resistors... very nice for a 3 watt resistor, and conveniently on sale at handmade audio (some values at least).
