Overview

The QRM8-026-02.0-L-D-A-GP-K-TR is a high-speed, 0.80mm pitch male pin connector array designed for mezzanine board-to-board applications. It features 52 total positions across two rows and includes an integrated ground plane to support high-signal integrity requirements. This surface-mount connector is equipped with alignment pins and a guide post system to ensure precise mating in dense electronic assemblies.

Why Choose This Part

The QRM8 series offers a rugged 0.80mm pitch design with a built-in ground bus to minimize crosstalk and improve EMI performance. Its 10 micro-inch gold plating ensures reliable contact over 100 mating cycles, while the pick-and-place pad and tape-and-reel packaging facilitate automated SMT assembly. The inclusion of alignment pins and guide posts simplifies blind mating in tight enclosures.

Applications

High-Speed Mezzanine Cards
Connecting daughter cards to motherboards where signal integrity and controlled impedance are required for high-speed data transfer.
Embedded Computing Modules
Used in COM Express or similar modular architectures to provide high-density I/O between processing cores and carrier boards.
Telecom and Networking
