Frequently Asked Questions
How many positions does the QTT-144-01-S-T have and what pitch does it use?
The QTT-144-01-S-T provides 132 positions in a single-row configuration with a 2.00 mm pitch, spanning a 3.486 inch body length. This high pin count and medium pitch make it well suited for power plane and multi-signal board stacking applications in servers, telecommunications chassis, and industrial backplane systems.
What contact material and finish does the QTT-144-01-S-T use for mating connections?
The QTT-144-01-S-T uses phosphor bronze as the base contact material with a gold (30 µin minimum) over nickel mating contact finish. The 30 µin gold plating provides excellent corrosion resistance and stable low contact resistance across the 132 mating positions, supporting reliable signal and power distribution over thousands of mating cycles.
In which board stacking applications is the QTT-144-01-S-T commonly deployed?
The QTT-144-01-S-T is commonly used in server backplanes, mezzanine card assemblies, and telecommunications line cards where a 132-position, 2.00 mm pitch board stacking connector is required for high-density power plane connections. Its 3.486 inch body length accommodates wide power distribution buses, and its gold-plated phosphor bronze contacts ensure signal integrity across multi-board stacking configurations in demanding environments.
