#447530 — Long term stability of matched resistors?

If I select metal foil resistors with 1% tolerance so that they match
to 0.1% can I expect that the matching keeps stable for a longer time
or will the values drift sooner or later to their 1% tolerance?
In other words: Do I need resistors with 0.1% initial tolerance for
long term 0.1% matching?

** Hang on a mo,

"metal foil" resistors are typically 0.01% tolerance or better.

Maybe you mean "metal film".

Yes, of course. I fear my technical english vocabulary is rather unsufficient.

Even if you buy 0.1% resistors, that does not mean that they will stay 
within 0.1% forever, nor that they will always stay matched even to the 
initially guaranteed 0.2%.

Some resistors have stability specifications, but these are usually so 
loose as to be fairly useless, except for extremely expensive resistors.

Vishay seems to have bought almost all of the precision resistor 
companies. If you want a second source it is getting difficult.

If the resistors are selected from the same manufacturing lot, are
used well below their specified voltage/power/temperature ratings
under similar operating conditions they should match fairly well. It's
hard to guarantee, though, absent manufacturer matching specs.

If the application is really critical and is a one-off, so presumably
less cost-sensitive,  you may be best off buying a matched pair in a
package.

Read the data sheet about drift, load life and so on. It's not just a
simple tolerance specification. The tolerance refers (usually) to
initial tolerance at a reference temperature (eg. 25°C) and before
soldering, aging etc. 

Generally, chances are excellent that resistors of similar or equal
resistance value from similar lots will match well over time, but
there are no guarantees, especially if the environment or service (eg.
pulses, large DC bias) is not benign. 

Since looser tolerance resistors may be made with inferior materials
or construction, they may tend to deviate more over time or
temperature etc. Or not.

We've been impressed with the long-term stability of the Susumo
surface-mount thinfilm resistors. Some of our products that depend on
them are showing drifts of low tens of PPMs per year, with lots of
other things contributing.

What specific resistor types did you have in mind?

Just ordinary metal film types like vishay CCF55 
(http://www.vishay.com/docs/31015/ccf55.pdf)
or thick film chip resistors with tempco of 100 ppm.
I do not develop products, I use them only in hobby projects.

Looks like the temperature coefficient will be a bigger error than
ageing.

The Susumu's typically have tempcos in the single digits of PPMs. Here
in the USA, we can get them inexpensively from Mouser or Digikey.

Hi Peter,

> Just ordinary metal film types like vishay CCF55
> (http://www.vishay.com/docs/31015/ccf55.pdf)

schau mal auf Seite 2 im eben zitierten Datenblatt unter Performance. Da 
stehts:
Je nach Umgebungseinfluß darf sich der Widerstandswert signifikant 
(Jeweils um 0,5%) verändern

In der Praxis werden abgeglichene Widerstände fast immer nah beieinander 
montiert (alleine schon wegen der thermischen Drift), da sollte dann 
auch bei beiden Widerständen ähnliches passieren. Aber wenn man sich 
darauf verlassen soll, dann sollte man wenigstens ein paar Testreihen 
aus verschiedenen Chargen testen.

Wenn es aber ohnehin Geld kostet, die Teile zu selektieren, dann ist es 
billiger gleich entsprechend eng tolerierte Widerstände zu kaufen.

So long

Marte

Sorry about the german writing here, but it is much easier for Peter an 
me ;-)

Google translates "so long" into English as "so long." It actually
sounds Asian to me.

Hi John,

> Google translates "so long" into English as "so long."

may be it is such a denglish word that "should" sound like english but 
really is a nativ german slang like "Handy" which means mobile but 
sounds like an english word and therefore more cool;-)

So long at the end of a paragraph means not more or les than "it's 
enough for now".

So long

Is "so long" originally German?

We'll happily steal from anyone.

(I'm 3/4 German myself, but I never learned the language. I pretend to
be Irish.)

afaui "so long" is an Americanization of the greeting shalom or salaam

To me "so long" is a form of "good bye", "till I see you again".
a parting thought, "so long, for now"

I've got direct male decent back four generations to a George Herold
who came over from the Deutschland, I'm probably less than 1/8 
German, but I've always felt more German than I am.

no sense of humour, preoccupied with order or take over the world German? ;)

Right, I'm totally none of that,  UB (my grad school) had an exchange 
program with a German school. (I'm thinking Wurtzburg, but that 
is probably wrong.)  I got to know many Germans who where both 
fun and hard working.  Some more this way, some more that... 
basically like everyone else.
