Hello all,

this might be a bit off topic, however is there a (easy or not) way to
tell the working voltage of a ceramic disc capacitor? I have tons of
these surplus or saved capacitors but often the working voltage is
marked when equal or higher than 1 kV. When I have to reuse a capacitor
in a high but not so high voltage circuit (let's say 200 Vdc) I never
know how to find the correct size or how to measure the insulation
voltage of the capacitor.
Fortunately film capacitor have a clear marking :-)
Best regards
