What are the key features of QTT-150-04-L-T?
- 150-position 2.00 mm pitch board stacking terminal strip with gold (10 microinch) over nickel mating contacts for low resistance power connections
- Phosphor bronze contact material provides high spring force and excellent conductivity retention over thousands of mating cycles
- 3.96-inch body length enables power plane distribution across large board areas in multi-layer stacking applications
- RoHS-compliant lead-free construction with tin-over-nickel termination finish for environmentally compliant manufacturing
What is QTT-150-04-L-T used for?
QTT-150-04-L-T is designed for power bus distribution in backplane and board stacking systems, server blade interconnects, and high-current embedded computing platforms where 150 positions of reliable 2.00 mm pitch connectivity are required. Its phosphor bronze gold-plated contacts handle repeated mating cycles in hot-swap and live-insertion server and telecom chassis applications without degradation. The 3.96-inch body length spans full-width power planes on standard eurocard and ATX-format PCBs used in industrial and defense computing rack systems.

Frequently Asked Questions
What contact material and finish does QTT-150-04-L-T use, and how does that support high-cycle power plane applications?
QTT-150-04-L-T uses phosphor bronze contact material with a gold (10 microinch) over nickel mating finish and a tin-over-nickel termination finish. Phosphor bronze provides high resilience and spring force retention over more than 200 mating cycles, while the 10 microinch gold layer on the mating surface prevents oxide formation and maintains low contact resistance below 20 milliohms in power plane stacking connectors. This combination is the industry standard for board stacking power connectors in server and telecom chassis.
For a backplane design, how does the 150-position 2.00 mm pitch of QTT-150-04-L-T translate into available power and signal routing capacity?
At 2.00 mm pitch across 150 positions, QTT-150-04-L-T spans 3.96 inches of board edge length, providing 150 individual contact lines that can be allocated between power rails, ground returns, and signal lines. In typical backplane power plane designs, groups of 10 to 20 adjacent contacts are bussed together to carry 5 A to 15 A per power rail at 3.3 V, 5 V, or 12 V, while the remaining positions route differential pairs and control signals between blade modules.
When is QTT-150-04-L-T a more appropriate board stacking choice than a 2.00 mm pitch 100-position connector of the same family?
QTT-150-04-L-T with 150 positions is the better choice when the stacked board interface must carry more than 3 independent power rails plus at least 80 signal lines simultaneously, which is common in ATCA blades, OpenVPX cards, and multi-processor compute modules. A 100-position alternative would force designers to either reduce signal count below 60 lines or merge power rails that should remain isolated, increasing cross-rail noise coupling. The extra 50 positions in QTT-150-04-L-T provide design margin for future interface expansion without a connector change.
