Q Strip™ High-Speed Mezzanine Connectors

Samtec Q Strip™ High-Speed Mezzanine Connectors are designed for high-speed board-to-board applications where signal integrity is essential. Q Strip connectors have surface-mount signal contacts and a surface-mount ground plane between the two rows of signals for improved electrical performance. Mated sets of Samtec Q Strip connectors are available in 8 different stack heights from 5mm (.197") to 30mm (1.180"). Options include guideposts for blind mate scenarios and alignment pins and locking clips for proper connector placement before reflow.
