What are the key features of QTT-150-01-L-T?
- 150-position board stacking connector at 2.00 mm pitch with 3.96 inch body length for large-scale power plane interconnection
- Phosphor bronze male contacts with 10 µin gold over nickel mating finish ensuring low contact resistance and reliable current-carrying capability
- Tin over nickel barrier termination finish compatible with lead-free reflow soldering and high-reliability PCB assembly processes
What is QTT-150-01-L-T used for?
The QTT-150-01-L-T is designed for high-current power plane distribution in server backplanes, telecom power distribution boards, and industrial power management systems. Its 150-position layout at 2.00 mm pitch enables massive parallel power and ground connections between stacked PCBs, reducing IR drop and thermal stress in high-load electronics. The robust phosphor bronze contacts support repeated board-stacking operations in field-serviceable rack-mounted equipment.

Frequently Asked Questions
What contact pitch and body length does the QTT-150-01-L-T provide for power plane applications?
The QTT-150-01-L-T uses a 2.00 mm pitch with a 3.96 inch (approximately 100.6 mm) body length, accommodating 150 positions for power plane board stacking. This large format and generous pitch facilitate high current distribution across server backplanes and industrial power boards where low contact resistance across many parallel power and ground pins is essential.
What contact material and finish does the QTT-150-01-L-T use and what does this mean for current handling?
The QTT-150-01-L-T features phosphor bronze contacts with 10 µin gold over nickel mating finish and tin over nickel barrier termination. Phosphor bronze provides excellent spring force retention and fatigue resistance, while gold plating ensures stable, low-resistance contact even after multiple board-stacking cycles, supporting reliable high-current power distribution in 150-position power plane assemblies.
For which high-density power distribution designs is the QTT-150-01-L-T board stacking connector typically specified?
The QTT-150-01-L-T is specified in server blade power distribution boards, telecom -48 V rectifier assemblies, and industrial UPS bypass switching modules. Its 150-position count at 2.00 mm pitch provides sufficient contact area for distributing hundreds of amperes across stacked PCBs in data center power shelves, where minimizing board-level resistance and supporting serviceable module replacement are critical design requirements.
How does the QTT-150-01-L-T compare to finer-pitch signal connectors for power plane stacking?
Unlike fine-pitch signal connectors at 0.050" or 1.00 mm pitch, the QTT-150-01-L-T uses a 2.00 mm pitch with larger contact cross-sections optimized for current capacity rather than signal density. Each 2.00 mm pitch position can carry substantially more continuous current than a 0.050" pitch signal contact, making the QTT-150-01-L-T the correct choice when the design requires 150 high-current power or ground connections between stacked boards.
