Overview
The QMS-026-06.75-L-D-A is a high-speed Q2 Power Rate board-to-board header featuring 52 positions across two rows on a 0.635mm (0.025 inch) pitch. This surface-mount connector includes an integrated ground plane (bus) to improve signal integrity and supports mated stack heights of 11mm or 13mm.
Why Choose This Part
This connector features a dedicated ground bus for superior crosstalk performance and EMI reduction. The inclusion of board guides and an outer shroud ensures robust mechanical alignment during mating, while the 10 micro-inch gold plating provides durable, low-resistance electrical contacts.
Applications
High-Speed Mezzanine Cards
Used to connect daughterboards to carrier boards where high signal density and controlled impedance are required.
Backplane Signal Distribution
Ideal for distributing high-frequency signals across parallel PCBs in networking or telecommunications equipment.
Industrial Computing Modules
