A well-logging tool for geological formation has a borehole. A housing that is to be positioned within the borehole includes an opening. An electrically conductive winding is carried by the housing. A feedthrough assembly includes an elongate electrical conductor having opposing first and second ends and a medial portion extending therebetween. The first end is coupled to the electrically conductive winding. An integrally formed, monolithic, dielectric layer sounds the elongate electrical conductor and includes a first enlarged diameter end portion surrounding the first end of the elongate electrical conductor and is positioned within the opening. A reduced diameter portion surrounds the medial portion of the elongate electrical conductor.
