An assembly for passing controlled impedance electrical signals between two different environments via feedthroughs in an electrically-conductive feedthrough block. The feedthrough has a signal coupling, a dielectric spacer surrounding the signal coupling, and a ground coupling surrounding the dielectric. The feedthrough is sealed to hermetically separate the two environments. One or both ends of the dielectric are recessed from the face of the block forming a gap. The gaps is filled with a potting material to form the hermetic seal.

An electrical connecter (400), such as a jack, has a mating end (402), a first barrel (404), an optional collar (406), a second barrel (408), a body end (410), a center receptacle (412), a first solid dielectric (502) at the mating end of the first barrel, and second solid dielectric (504) at the body end (410) of the second barrel. The first section of the barrel has a smooth and uniform outer wall (404A). This allows the inner diameter (DIS) of the first section of the barrel to be increased without reducing the thickness (T) of the first section of the barrel below a minimum value, and allows the outer diameter (DOC) of the center conductor in the vicinity of the first section of the barrel to be increased to provide for a greater current-handling capability. This provides for maintaining a desired impedance even with the greater current-handling capability.
