ABSTRACT:
A low-inductance capacitor, and related method for manufacturing it, of a type that includes two foil strips and two dielectric strips interleaved together and wound into a spiral capacitor roll. The two foil strips are offset laterally with respect to each other and the roll is flattened such that its two sides are defined by oblong spiral projections of the foil strips. Two separate U-shaped clamps compressively grip the two oblong spiral projections, to form electrical terminals for the capacitor roll, each terminal in secure electrical contact with all of the successive windings of the corresponding foil strip. The capacitor roll is adapted for mounting on a foil strip transmission line, the combination providing an extremely low inductance.
