Abstract: A filtered header assembly for connection to a printed circuit board having a plurality of circuit traces thereon comprises a connector housing carrying a plurality of spaced pin terminals whose ends remote from the connector housing are adapted to be electrically connected to the circuit traces on the printed circuit board and a filter means including capacitors operatively connected with the pins and a ground for filtering electrical noise passing through the pins. The filter means comprises a filter pack subassembly which is simultaneously slidably connected to each of the plurality of pins and with the filter pack subassembly including a housing means having a plurality of openings therethrough through which the pins extend, an array of spaced capacitors in the housing and located adjacent said pins and biasing means for biasing the array of capacitors into engagement with the pins.
