    Teflon capacitor duration

    whats the shelf life for teflon dielectric capacitors?

    these appear to be a decent deal but they are NOS and might be far off their spec

    8000Vs and rather large, do you need such a high voltage?

    Those caps are likely damaged due to improper storage conditions and it seems highly unlikely they will perform anywere near their claimed specs.

    Re: Teflon capacitor duration

    As they're not electrolytic, that's one possible failure mode side-stepped.

    But, IMHO, if you're playing with such voltages, don't risk it. Buy the 'good stuff', and install with due care lest the 'magic smoke' escape...
