A filter assembly includes a printed circuit board having a filtering circuit and a ground plane. A body receives the printed circuit board. The printed circuit board has at least one tab, and the body has a respective slot for receiving each tab, aligning the printed circuit board with the body. The body is shaped so as to provide a first cable connector at one end. The ground plane of the printed circuit board is connected to an inner wall of the body by solder. A nut fits on an end of the body opposite the cable connector of the body. The nut provides a second cable connector at an end opposite the first cable connector. The nut is connected to the body by solder along a periphery of the nut to form a water tight seal. The solder joining the nut to the body is continuous with the solder connecting the ground plane to the body. A pair of terminals are electrically connected at opposite ends of the printed circuit board. Each of the terminals has a slot sized to receive a respective end of the printed circuit board and may form a friction fit between the printed circuit board and the terminals.
