Hi all,
I am wondering if the outside metal body of russian caps (K40Y-9, teflon...) is insulated or not. I mean if it should touch some wire or other component in a point-to-point circuit is there any risk of short? Should they be wrapped with some heat-shrinking plastic or can be safely left alone?
Thanks

They are insulated from the actual capacitor inside; you can confirm that with ohm and/or capacitance measurements from case to terminal.
As far as the case, it is conductive, so anything that comes in contact with it is electrically tied to the case. Two components or one component and chassis creates an undesired short. I don't heat shrink mine, I either let it hang in free air or bond it to the chassis. If you intend on having components touching the case, I would suggest some heat shrink.
Some claim shielding behavior by tying the case to earth; I haven't noticed any difference.
