Frequently Asked Questions
What contact material and finish does the QTT-117-04-G-T use for its 51-position contacts?
The QTT-117-04-G-T uses phosphor bronze contact material with 20 micro-inch gold over nickel mating finish, providing high spring force for reliable contact pressure, excellent conductivity, and corrosion resistance suitable for repeated mating cycles in power plane board stacking applications.
What board stacking applications benefit from the QTT-117-04-G-T's 51-pin 2.00 mm pitch design?
Server power distribution boards, backplane-to-compute card stacking assemblies, and industrial power control modules requiring 51 contacts at 2.00 mm pitch use this connector to deliver distributed power and ground signals across multiple board layers with low resistance and mechanical stability.
What are the key body dimensions of the QTT-117-04-G-T and why do they matter?
The QTT-117-04-G-T body measures 1.353 inches long, 0.236 inch wide, and 0.512 inch deep, providing a narrow footprint that allows dense placement across power plane regions while the 0.512 inch depth ensures sufficient contact engagement depth for reliable 51-pin mating under vibration.
Is the QTT-117-04-G-T RoHS compliant, and how does its gold termination finish aid assembly?
Yes, the QTT-117-04-G-T is RoHS compliant (Pb-free) with a gold termination finish backed by a nickel barrier, ensuring excellent solderability in lead-free reflow processes at 260 °C peak temperature and long-term resistance to intermetallic growth at the solder joint over years of service.
