The Samtec QMS-078-06.75-L-D-PC4 is a high-density mezzanine connector with 156 positions arranged in two rows at a 0.64mm pitch. It features a header, outer shroud contacts design and offers a mixed mounting configuration: signal pins are surface mount while power pins are through-hole (PC4 option). The insulator is made of liquid crystal polymer and terminals are phosphor bronze with gold plating over nickel on signal pins and ground plane, with tin on tails.
Electrical ratings include 2.6A per signal pin (2 pins powered), 4.0A per power pin (4 pins powered per end), and 15.7A per ground plane. The voltage rating is 300 VAC when mated with the QFS series. Operating temperature range is -55°C to +125°C. The connector includes a board guide, ground bus/plane, and eight power pins.
Designed for mezzanine board-to-board stacking, the mated stacking heights are 11mm and 13mm. The part is RoHS3 compliant and lead-free solderable. It is suitable for applications requiring both signal and power connections in a compact footprint.
