Frequently Asked Questions
What contact finish does the QTT-115-03-L-T use and why does it matter for board stacking?
The QTT-115-03-L-T uses gold (10 microinch) over nickel contact finish on mating surfaces, paired with tin-nickel termination plating. Gold plating provides low contact resistance and high corrosion resistance, which is critical in board stacking applications with 45 positions where consistent electrical performance across all contacts is needed for reliable power and signal distribution.
How does the 2.00 mm pitch of the QTT-115-03-L-T compare to standard 2.54 mm pitch connectors for high-density designs?
The QTT-115-03-L-T operates on a 2.00 mm pitch, which is tighter than the standard 2.54 mm (0.100 inch) pitch used in many legacy connectors. This 20% reduction in pitch allows 45 positions to fit within a 1.195 inch body length, enabling higher density connections in compact modular systems and backplane designs without sacrificing the phosphor bronze contact strength or gold-plated reliability.
In which industrial or computing systems is the QTT-115-03-L-T a good fit for power plane distribution?
This connector is well-suited for industrial embedded computing racks, server backplanes, FPGA development platforms, and modular instrumentation systems where multiple PCBs must share power planes across 45 pins at 2.00 mm pitch. Its phosphor bronze contacts rated for board stacking configurations deliver the mechanical resilience needed to maintain reliable connections in environments with vibration, thermal expansion, and repeated mating cycles.
What body dimensions should a PCB designer use when creating a footprint for the QTT-115-03-L-T?
The QTT-115-03-L-T has a body length of 1.195 inches (30.35 mm), a body depth of 0.433 inches (11.0 mm), and a body breadth of 0.236 inches (5.99 mm). Designers should reference the SAMTEC QTT series datasheet for the full recommended PCB land pattern, as the 45-position, 2.00 mm pitch layout requires precise pad spacing to ensure proper solder joints and board alignment.
