Frequently Asked Questions
How many positions does the QTT-149-02-G-T provide and at what pitch for board stacking?
The QTT-149-02-G-T provides 147 positions in a dual-row configuration at 2.00 mm pitch, with a 3.881 inch body length. Its phosphor bronze contacts finished with 20 micro-inch gold over nickel ensure low contact resistance across all 147 connections in power plane stacking applications.
In which backplane or server designs does the QTT-149-02-G-T deliver the highest value?
Telecom chassis backplanes, server blade enclosures, and high-performance computing mezzanine cards benefit most from the 147-position 2.00 mm pitch layout of the QTT-149-02-G-T, as the wide 3.881 inch connector distributes power across multiple voltage rails with minimal impedance in a single board-stacking interface.
What contact material and finish does the QTT-149-02-G-T use, and how does this affect connector longevity?
The QTT-149-02-G-T uses phosphor bronze contacts with 20 micro-inch gold over a nickel barrier for both mating and termination surfaces. This finish provides excellent corrosion resistance and maintains low contact resistance over thousands of mating cycles, extending connector lifespan in rack and backplane environments subject to repeated board insertion.
