I am assuming capacitors made with two rolled metal plates, offset to 
the sides
so the contacts are at the sides of the rolls. In this way there is no 
extra
inductance due to coiled structures. The inductance is then practically the
inductance of a solid metal conductor with the shape of the capacitor.
