Frequently Asked Questions
What contact finish does the QTT-114-04-S-T use and why does it matter for board stacking applications?
The QTT-114-04-S-T uses 30 µin gold over nickel on mating surfaces, which provides excellent corrosion resistance and maintains low contact resistance below 20 mΩ after repeated mating cycles. For board stacking applications that may be mated and unmated during system maintenance, gold plating ensures reliable signal and power transfer without oxidation degradation.
How does the 2.00 mm pitch of QTT-114-04-S-T compare to standard .100" pitch connectors for power distribution?
The 2.00 mm pitch of the QTT-114-04-S-T is tighter than the standard .100" (2.54 mm) pitch, fitting 42 positions into a body length of approximately 1.116 inches. This finer pitch allows higher pin density in power plane designs compared to .100" alternatives of equal length, enabling more current-carrying pins within the same board edge footprint.
Which system architectures benefit most from using the QTT-114-04-S-T as a board stacking connector?
Server blade assemblies, FPGA mezzanine card stacks, and industrial modular I/O racks benefit most from the QTT-114-04-S-T. Its 42-position layout can carry both power planes and signal lines simultaneously, and the 2.00 mm pitch accommodates high-density routing in boards where connector length must stay under 30 mm.
What material properties of QTT-114-04-S-T contacts contribute to mechanical durability in high-vibration environments?
The QTT-114-04-S-T uses phosphor bronze contact material, which has a tensile strength of approximately 500 MPa and excellent spring-back characteristics, maintaining consistent contact normal force across temperature cycles from -55°C to +125°C. This makes the connector suitable for industrial and aerospace board stacking applications subject to mechanical vibration.
