Frequently Asked Questions
What contact finish does the QTT-116-03-L-T use, and why does it matter for signal integrity?
The QTT-116-03-L-T uses gold (10 microinch minimum) over nickel on mating surfaces, which provides a contact resistance typically below 20 milliohms and excellent resistance to fretting corrosion. This gold finish is critical for maintaining low-loss signal integrity on high-cycle board stacking applications where tin-tin contacts would degrade rapidly.
How does the 2.00 mm pitch of the QTT-116-03-L-T compare to finer-pitch board stacking alternatives for power distribution?
The 2.00 mm pitch of the QTT-116-03-L-T provides wider pin spacing than 1.27 mm or 0.8 mm alternatives, increasing the per-pin current carrying capacity (typically 3 A to 5 A per contact) and improving creepage distance for higher-voltage power planes. This makes it better suited for power distribution applications versus signal-density-optimized fine-pitch alternatives.
In what stacked PCB system architectures is the QTT-116-03-L-T most commonly deployed?
The QTT-116-03-L-T is commonly used in ATCA blade servers, VME-based industrial computers, multi-layer power distribution boards, and ruggedized embedded computing chassis. Its 48-position 2.00 mm pitch format handles simultaneous power and signal routing across board stacks at voltages up to 250 V, supporting both high-current DC rails and logic-level digital signals within the same connector housing.
What body dimensions should PCB designers consider when laying out a footprint for the QTT-116-03-L-T?
The QTT-116-03-L-T has a body length of 1.274 inches, body depth of 0.433 inches, and body breadth of 0.236 inches. Designers must reserve these keepout dimensions in their PCB layout, and account for the mating stack height and tolerance when designing the mechanical enclosure or mating board standoff spacing.
