The MKT Z-Cap capacitors from Jantzen Audio are made of a high-quality metallized polyester film. They offer a longer life and better sound properties than electrolytic capacitors. When it is not possible to use metallized PP foil capacitors as an alternative to electrolytic capacitors for high value positions on crossovers due to their size, MKT-Zs are an excellent alternative. Typically, MKT capacitors are offered with a voltage of 160VDC, but by using a thinner dielectric of 100VDC, MKT Z-Caps benefit from a reduced size. Because of their shape, they can be stacked more easily when coupled in parallel and therefore take up much less space than equivalent value Cross Cap capacitors.
