A compact electrical connector has first contacts () with a first characteristic impedance (50 ohms) and second contacts () with a second characteristic impedance (100 ohms), with each set of contacts having a separate electrical ground (G, G). The first contacts lie in passages of a first insulative holder (), with the first contacts arranged in three rows () wherein the middle row is offset from the top and bottom rows to maintain a constant contact spacing. The second contacts () lie in two vertically elongated insulative holders () that each lies at one end of the first holder, with each holder having a grounded second contact () and with each holder projecting into a recess () at the end of the frame that receives the first holder.

Connector with isolated grounds

A shield is provided that blocks high frequency EMI (electromagnetic interference) from reaching circuitry that is connected to pins of a filter connector. The filter connector includes a plurality of pins () that extend through holes () in first boards (), with each pin joined by a solder joint () to a signal trace () that surrounds the pin hole. Filter components such as capacitors (), each have one terminal () joined to a signal trace and another terminal () joined to a ground trace (), with a gap () between the traces. Second boards () are provided that each lies facewise adjacent to a first board and that each carries a shield trace () that covers the gap between signal and ground traces. The pin-receiving hole in each second board has a circular portion and has a notch () therein though which a solder dispenser () can fit to dispense solder directly into the space between and on the pin and the signal traces.
