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.
