Claim 9:
10. A high-voltage self-healing metallized polymer capacitor formed in the vacuum, the capacitor comprising:
multiple internal sections of the capacitor, said sections electrically-connected in series; and
metallized electrodes in each of the multiple internal sections;
wherein at least one of said metallized electrodes has
(A) a first electrode portion having a first thickness limited by first and second surfaces of the at least one of said metallized electrodes,
wherein the first electrode portion is located with said first thickness extending throughout an active capacitor area and laminated between and in contact with a first surface of a first non-thermoplastic polymer dielectric layer and a second surface of a second non-thermoplastic polymer dielectric layer of said capacitor, and

(B) a second electrode portion having a second thickness limited by a third surface of the at least one of said metallized electrodes and the second surface of the at least one of said metallized electrodes, the second thickness being greater than the first thickness to increase mechanical strength of a capacitor's termination,
wherein said second electrode portion is located with said second thickness present
(i) between the first and second polymer dielectric layers such that
the third surface of the at least one of said metallized electrodes is in direct physical contact with the first surface of the first non-thermoplastic polymer dielectric layer along said second electrode portion, and
the second surface of the at least one of said metallized electrode is in direct physical contact with the second surface of the second non-thermoplastic polymer dielectric layer along said second electrode portion, and

(ii) outside the first and second non-thermoplastic polymer dielectric layers such each of the third surface and the second surface of the at least one of said metallized electrode is in contact, along the second electrode portion, with a material different from a material of the first and second non-thermoplastic polymer dielectric layers,

wherein adjacent non-thermoplastic polymer dielectric layers of the capacitor alternate with said metallized electrodes to form a non-wound stack of layers devoid of air gaps between constituent layers of the stack.
