What are the key features of QTT-150-03-G-T?
- 150-position 2.00 mm pitch board stacking terminal strip spanning 3.96" body length for ultra-high-density power plane connectivity
- 20 microinch gold (Au) over nickel (Ni) mating contact finish delivers contact resistance below 10 mΩ and supports over 500 mating cycles
- Phosphor bronze contact material provides superior spring force retention and resistance to stress relaxation in high-cycle and elevated-temperature applications
- RoHS-compliant (Pb-free) construction with gold termination finish for compatibility with lead-free soldering processes up to 260°C peak
What is QTT-150-03-G-T used for?
The QTT-150-03-G-T is designed for high-density power plane distribution in server backplanes, ATCA/VME chassis, and multi-board computing modules where 150 contacts must be stacked in a 3.96" linear footprint at 2.00 mm pitch. The phosphor bronze contacts and 20 µin gold mating finish ensure stable low-resistance connections in high-vibration rack-mounted environments. It is also used in telecom line cards and industrial control backplanes requiring board-to-board power and signal integrity across thousands of insertion cycles.

Frequently Asked Questions
What contact finish and material does the QTT-150-03-G-T use, and how does this affect its mating cycle rating?
The QTT-150-03-G-T uses 20 microinch gold (Au) over nickel (Ni) on the mating interface and phosphor bronze as the contact base material. This combination supports more than 500 mating cycles while maintaining contact resistance below 10 mΩ, making it suitable for backplane assemblies that require periodic board removal for maintenance or reconfiguration.
How does the 2.00 mm pitch and 150-position configuration of the QTT-150-03-G-T compare to 2.54 mm pitch alternatives for board stacking?
At 2.00 mm pitch across 150 positions, the QTT-150-03-G-T achieves a body length of 3.96 inches, which is approximately 22% shorter than an equivalent 2.54 mm pitch connector would require for the same position count. This makes it preferable in ATCA or VME 6U chassis where backplane real estate is constrained and multiple 150-position connectors must fit within a 233 mm board height.
For which power distribution topologies is the QTT-150-03-G-T best suited in a server backplane design?
The QTT-150-03-G-T is best suited for distributed power plane designs in server backplanes where multiple voltage rails (e.g., 12V, 5V, 3.3V, and ground) must be routed through a 150-contact interface at current levels up to 1A per contact. Its 2.00 mm pitch allows grouping of power and ground contacts into dedicated zones across the 3.96-inch connector body, reducing impedance and minimizing ground bounce in high-speed digital systems.
Is the QTT-150-03-G-T compliant with RoHS requirements, and what soldering process does the gold termination support?
Yes, the QTT-150-03-G-T is RoHS compliant (Pb-free code: Yes). The gold (Au) over nickel (Ni) termination finish is compatible with lead-free wave and selective soldering processes at peak temperatures of 250°C to 260°C, and the through-hole tail geometry supports conformal coating after soldering for moisture protection in harsh industrial environments.
