What are the key features of QTT-144-04-F-T?
- 132 positions on 2.00 mm pitch in a board-stacking configuration for high-density power plane interconnection
- Gold flash over nickel mating contact finish provides corrosion resistance and reliable low-resistance connections
- Phosphor bronze contacts deliver strong spring-back force and stable retention across thermal cycling
- RoHS-compliant tin-over-nickel termination finish is compatible with lead-free soldering processes
What is QTT-144-04-F-T used for?
The QTT-144-04-F-T is designed for board-stacking power plane distribution in server backplanes, ATCA modules, and high-density computing systems where 132 power and signal lines must pass between stacked PCBs through a single compact connector. Its 2.00 mm pitch and 3.486 inch body length suit rack-mounted networking and storage equipment requiring high current capacity per pin position. The connector is also used in industrial computing platforms and modular embedded systems where reliable board-to-board power distribution is critical.

Frequently Asked Questions
How many positions does the QTT-144-04-F-T provide, and how are they arranged for board-stacking use?
The QTT-144-04-F-T provides 132 positions on a 2.00 mm pitch in a board-stacking connector format. The 3.486 inch body length accommodates the full 132-pin count in a single row, allowing a backplane or mezzanine card to distribute power rails and high-speed signals between stacked PCBs without multiple smaller connectors.
What contact materials and finishes does the QTT-144-04-F-T use, and why do they matter for power distribution?
The QTT-144-04-F-T uses phosphor bronze contacts with gold flash over nickel on the mating surfaces and tin over nickel on the termination side. Phosphor bronze provides high spring force to maintain stable contact resistance in power distribution applications, and the gold flash finish prevents oxidation that would increase contact resistance and cause heating on high-current pins carrying several amperes per contact.
Is the QTT-144-04-F-T compatible with RoHS-compliant lead-free soldering processes?
Yes, the QTT-144-04-F-T carries a RoHS-compliant (Pbfree) designation and uses tin over nickel on the PCB termination side, which is fully compatible with lead-free reflow and wave soldering processes. The tin termination withstands peak reflow temperatures of 260°C used in standard lead-free assembly profiles without degrading solder joint quality on the 2.00 mm pitch pads.
When would a designer choose the QTT-144-04-F-T over a 2.54 mm pitch board-stacking connector?
A designer selects the QTT-144-04-F-T's 2.00 mm pitch over a 2.54 mm pitch alternative when the target PCB footprint is constrained and the 132 required positions must fit within 3.486 inches. At 2.54 mm pitch, the same 132 positions would require approximately 4.4 inches, a 26% longer connector body that may not fit within standard ATCA or CompactPCI slot widths. The 2.00 mm pitch also reduces board real estate consumed by the connector pair.
