Key Features
- 60-position, 0.50mm pitch Q Strip board stacking connector with gold flash contact finish for low-resistance, high-cycle mating in high-density PCB stacks
- Integrated ground plane terminal strip design enhances signal integrity and reduces crosstalk at high-frequency operation in stacked board assemblies
- Phosphor bronze contacts with tin (Sn) over nickel (Ni) solder termination provide reliable mechanical spring force and RoHS-compliant soldering compatibility
Applications
The QTH-030-03-F-D is designed for high-speed board stacking in FPGA mezzanine modules, network switch line cards, and embedded computing carrier boards requiring 60 signals at 0.50mm pitch with excellent ground isolation. Its ground plane terminal strip reduces electromagnetic interference at multi-GHz data rates, making it ideal for SerDes and high-speed differential signal routing. The compact 0.787 inch body length allows dense multi-board stacking with minimal signal path degradation.

Frequently Asked Questions
How does the QTH-030-03-F-D's ground plane terminal strip improve signal integrity at high data rates?
The QTH-030-03-F-D integrates a ground plane within the 60-position, 0.50mm pitch terminal strip structure, which reduces crosstalk and electromagnetic interference between adjacent signal lines. This makes it particularly effective for SerDes links, PCIe, and differential signal pairs operating at multi-GHz frequencies in stacked FPGA and network switch board assemblies.
What contact materials and finishes does QTH-030-03-F-D use to ensure reliable mating in high-cycle board stacking applications?
The QTH-030-03-F-D uses phosphor bronze contacts with gold flash mating surface finish and tin (Sn) over nickel (Ni) barrier termination finish. Phosphor bronze delivers excellent spring properties for sustained contact normal force across multiple mating cycles, while gold flash minimizes contact resistance and oxidation in high-speed 0.50mm pitch board stacking interfaces.
What overall body dimensions should a PCB layout engineer allocate for the QTH-030-03-F-D on a carrier board?
The QTH-030-03-F-D measures 0.787 inch (approximately 20mm) in length, 0.235 inch (approximately 6mm) in breadth, and 0.404 inch (approximately 10.3mm) in depth. These dimensions govern the PCB real estate reserved for the 60-position board stacking connector and the keepout zone around mating area in high-density mezzanine layouts.
