Overview

The QFS-026-04.25-H-D-RF1 is a 52-position high-speed rugged socket strip from Samtec's Q2 series, featuring a 0.635 mm pitch and an integrated ground plane. Designed for board-to-board applications, it provides high-signal integrity and is rated for operation up to 125 degrees Celsius. This specific variant includes an RF1 option for improved shielding and mechanical stability in demanding environments.

Why Choose This Part

The integrated ground plane significantly reduces crosstalk and improves impedance matching for high-speed differential pairs. Its 30 micro-inch gold plating and phosphor bronze contacts ensure high reliability over a wide temperature range of -55 to 125 degrees Celsius. The SMT design and liquid crystal polymer housing support standard lead-free reflow soldering processes.
