In plastic foil capacitors generally no impregnation is needed and here one has been obliged to use aluminum (Al) because of its better chemical resistance. Now, however, some corrosion resistant alloys are introduced with the same advantageous characteristics as zinc. The metallization layer is thinner than 0.1 μm with typical values around 0.02 to 0.05 μm (0.8 to 2
