Frequently Asked Questions
What contact finish does the QTT-115-04-L-T use, and why does it matter for power applications?
The QTT-115-04-L-T uses 10 µin gold over nickel on mating contacts, which provides very low contact resistance and excellent corrosion resistance. These properties are critical in power plane stacking applications where consistent current flow across 45 positions must be maintained over many mating cycles.
How does the 2.00 mm pitch of the QTT-115-04-L-T compare to standard board stacking connectors?
At 2.00 mm pitch with 45 positions, the QTT-115-04-L-T offers a moderate-density footprint suited for power plane routing between stacked PCBs. Compared to 1.27 mm pitch alternatives, the 2.00 mm spacing provides greater current-handling capacity per contact and eases PCB routing for power signals.
In which system architectures is the QTT-115-04-L-T most commonly used?
This 45-position board stacking connector at 2.00 mm pitch is commonly used in server blade enclosures, FPGA development platforms, and modular industrial controllers where multiple PCBs must share power planes. The gold contact finish and phosphor bronze construction support reliable power distribution in high-cycle, thermally demanding environments.
