Frequently Asked Questions
How many positions does QTT-149-01-S-T provide, and what pitch does it use?
QTT-149-01-S-T provides 147 positions in a single-row configuration at 2.00 mm pitch. This large position count makes it suitable for applications requiring simultaneous routing of power planes and signal lines between stacked boards, such as backplane interconnects in server or industrial computing systems.
What contact finish does QTT-149-01-S-T use, and how does it affect mating performance?
QTT-149-01-S-T uses 30 µin (microinch) gold over nickel as the mating contact finish and tin with nickel barrier on the termination side. The 30 µin gold plating delivers low contact resistance across 147 positions and resists oxidation, maintaining reliable electrical performance through repeated mating cycles in board-stacking assemblies.
What board dimensions does the QTT-149-01-S-T body occupy on the PCB?
The QTT-149-01-S-T body measures 3.881 inches (98.6 mm) in length, 0.276 inches (7.0 mm) in depth, and 0.236 inches (6.0 mm) in breadth. Designers must reserve this footprint on the PCB edge or internal area when planning the stacking layout for embedded computing or backplane applications.
