Identification help of soviet passive component

(1/3) > >>

Vtile:
Hi.

I do have a handfull of these components (see pictures) past 20+ years or so. I again found the old can I have them in.

My problem is that I just can't identify or measure them. The resistance seems to be over 1Gohms and even the capacitance seems to be that small that I do not have any even close to reliable measuring device in my disposal. I just were measuring roughly 0.5 pA with 10Vdc exidation voltage, but again I'm pushing my equipment on its limit.

Anyone have idea, I have no other idea than that they are from old Riga radio factory, by the story told when they were handed to me.

rob77:
that should be a capacitor.. probably you can't measure because it's only 15pF

ataradov:
Those are capacitors and they are not great. Their real value is in the silver and other precious metal contents. If you can get a lot of them, they pay well. Their plates are made out of pure silver.

BrokenYugo:
15pf 10%? Parallel the device in question with 100pf if you don't have anything that reads low enough.

Vtile:
Ok. Thanks.

That is what I were thinking - since they do seem to have less reactance than resistance - but could not verify properly.

A trash more or less, I have a about a big handfull of those so not worth to try sell / salvage.
