A dielectric component is fabricated from a dielectric material and includes a base panel member and a plurality of isolation panel members. The base panel member has a first base panel member surface. The plurality of isolation panel members is connected to and projects perpendicularly from the first base panel member surface. The plurality of isolation panel members are disposed apart from and extend parallel to one another to form a plurality of isolation channels. An electrical connector assembly includes an electrical connector housing and the dielectric component. Consecutive ones of a plurality of terminal pin portions projecting from the electrical connector housing are isolated from one another by consecutive ones of the plurality of isolation panel members such that the terminal pin portions are disposed in the isolation channels and are therefore isolated from one another. The electrical connector assembly might also incorporate a printed circuit board.
