An electrical connector includes mounting posts for insertion into through-holes of a printed circuit board. The connector includes a connector housing having an upper connection surface and an lower board mounting surface. A pair of mounting posts extend from the lower mounting surface adjacent each end of the connector. Each of the mounting posts is insertable into a through-hole in the printed circuit for frictional engagement with the walls of the through-hole. The mounting posts include curved portions for engagement with the walls of the through-holes. The curved portions of the mounting posts have a radius of curvature which is substantially less than the radius of curvature of the through-holes to compensate for variations in tolerances as between the mounting post and the through-holes.

An improved electrical filter connector comprises a capacitor sub-assembly including an insulative substrate, a plurality of capacitors soldered thereto and a ground spring. The ground spring is soldered to the ground terminations of the capacitors, the ground spring having a resilient portion for electrical engagement with conductive ground traces on a system circuit board. First terminations of the capacitors are electrically individually connected to respective contacts of the electrical connector. Second capacitor terminations are electrically connected to the ground strip. The capacitors are preferably of the discrete, monolithic chip type, having a dielectric body spaced between the electrical terminations thereof. A quantity of curable dielectric material is disposed on the dielectric bodies between each of the capacitor terminations to provide an enhanced dielectric medium to increase the capability of the connectors to withstand higher voltages during power surges.

An improved method of making an electrical filter connector includes the steps of providing a substrate with a plurality of metallized openings therethrough for electrical individual attachment to electrical contacts of the connector. The substrate is further provided with a metallized strip on a surface thereof spaced from the metallized openings. A plurality of capacitors are attached to the substrate. First conductive capacitor terminations are individually electrically attached to respective portions of the metallized openings and second conductive capacitor terminations are electrically attached in common to the metallized strip. A curable dielectric material is applied onto the dielectric body of each capacitor between each of the conductive terminations thereof. Each of the electrical contacts of the connector is electrically attached to a respective one of the metallized openings of the substrate.
