# QSH-040-01-F-D-DP-A-K-TR (Component)
## Description
High-Speed Differential Pair Board-to-Board Socket Connector – 80-position differential pair mezzanine socket connector designed for high-speed board-to-board interconnects, FPGA platforms, networking equipment, industrial control, embedded computing, and high-speed communication systems. Features a 0.50 mm pitch, 2-row surface-mount (SMT) design, and 2 A current rating per contact with a 175 VAC voltage rating. Part of Samtec's Q Strip® QSH series, it includes differential pair signal routing, an integrated ground plane (Ground Bus) for improved signal integrity, alignment pins, and gold-plated phosphor bronze contacts (3 µin / 0.076 µm) for high reliability and repeated mating cycles. Supports multiple mating stack heights (5 mm to 25 mm), utilizes an LCP (Liquid Crystal Polymer) housing, operates over a −55°C to +125°C temperature range, and is supplied in a tape-and-reel package for automated assembly.
