Overview
The QFS-026-04.25-L-D-A is a 52-position high-speed socket strip featuring a 0.635mm (0.025 inch) pitch and an integrated ground plane for improved signal integrity. This surface-mount receptacle is part of the Q2 series, designed to support mezzanine board-to-board applications with stack heights ranging from 10mm to 14mm. It utilizes Samtec high-speed contacts with 10 micro-inches of gold plating and includes alignment pins for precise PCB placement.
Why Choose This Part
The integrated ground plane significantly reduces crosstalk and improves performance in high-speed differential pair routing. Its versatile design supports multiple stack heights when paired with different QMS series headers, and the alignment pins ensure repeatable SMT assembly quality.
