Frequently Asked Questions
Why is the QTT-117-02-S-T classified as a power plane connector, and what current capacity does the 2.00 mm pitch allow?
The QTT-117-02-S-T is designated for power plane applications because its 51 contacts at 2.00 mm pitch can carry higher per-pin current compared to fine-pitch signal connectors. Each phosphor bronze contact with 30 µin gold plating supports approximately 1 A to 3 A per pin depending on thermal conditions and board layout.
How does the 30 µin gold mating finish on QTT-117-02-S-T benefit high-cycle applications?
A 30 µin gold (Au) over nickel finish on the mating surface provides significantly greater wear resistance than the standard 10 µin gold, supporting connector mate/unmate cycles exceeding 500 cycles while maintaining stable contact resistance below 20 mΩ in board stacking power distribution assemblies.
In which stacked PCB architectures is QTT-117-02-S-T typically used instead of press-fit or through-hole power connectors?
QTT-117-02-S-T is preferred in board stacking configurations where a 1.353-inch footprint must carry 51 power or ground lines between parallel PCBs at 2.00 mm pitch. It suits server blade interconnects, modular industrial controllers, and embedded computing racks where SMT assembly and field-swappable board modules are required.
