Ruthenuim oxide versus metal film in resistors
Default Ruthenuim oxide versus metal film in resistors

Hi!

This belongs maybe in tweak department but I wonder if there are any technical differencies between ruthenuim oxid (in plain 1206, 0805 etc SMD's) and ordinary metal film 0,6 W hole mounted?

I know so far that the SMD types are much worse in temperature stability probely also in long term stability but how about noise and other defects?

And if we come into the tweak area: Do they sound bad or good compared to the ordinary hole mounted types?

Actually Holco's 0.1% SMD resistors have better temp stability (10ppm) than their thru-hole variant (H8) at 25ppm.

Food for thought.

All,

are the SMT Ruthenium oxide resistors magnetic to some degree?

Harry,
couldn't you have simply swallowed your P.S.? Now this would have shown some improvement ...

and, thanx for the linx
