QSE-040-01-C-D-A-K Description

Short technical summary and product information.

The Samtec QSE-040-01-C-D-A-K is a high-density mezzanine receptacle part of the QSE series. It features 80 positions arranged in 2 rows with a 0.8mm pitch, designed for surface mount soldering. The contacts are phosphor bronze with a 50µin gold finish, ensuring reliable conductivity and corrosion resistance. The insulator is made of liquid crystal polymer, suitable for high-temperature processing.

 

This connector supports multiple mated stacking heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, providing flexibility in board-to-board applications. The current rating is 2A per pin (with 2 pins powered) and 23A per ground plane. The voltage rating is 225VAC when mated at a 5mm stack height. Operating temperature ranges from -55°C to +125°C, and it is rated for 100 mating cycles.

 

Additional features include an integrated board guide, a ground bus (plane) for improved signal integrity, and a pick-and-place pad (the -K option uses a polyimide film pad). The component is lead-free solderable and meets SMT lead coplanarity of 0.10mm maximum. Default packaging is tray; tape and reel options are available with the -TR suffix.
