- Integrated ground plane between signal rows provides controlled 50-ohm impedance and reduces crosstalk in high-frequency PCB designs
- Q Strip architecture with low-profile terminal design minimizes stub length and signal reflection for clean eye diagrams at 10 Gbps and beyond
Applications
QTH-030-05-L-D-A-K is suited for high-speed board-to-board interconnects in FPGA evaluation platforms, high-performance computing mezzanine cards, and SerDes line card interfaces requiring clean signal transmission at data rates of 10 Gbps or higher. Its integrated ground plane and 0.50 mm pitch design support differential pairs with controlled 50-ohm impedance, making it ideal for PCIe, SATA, and custom high-speed serial links. Engineers use it in telecommunications and networking equipment where signal integrity margins are tightly specified.

Frequently Asked Questions
What pin count and pitch does QTH-030-05-L-D-A-K offer for high-speed board interconnects?
QTH-030-05-L-D-A-K provides 60 positions on a 0.50 mm pitch in a dual-row Q Strip layout, yielding 30 contacts per row. The 0.50 mm pitch is half the density of standard 1.00 mm board-to-board connectors, enabling 60 signals — including differential pairs — in a footprint of roughly 15 mm by 3 mm. This compact geometry is essential for FPGA mezzanine and high-density line cards where connector real estate is limited.
How does the integrated ground plane in QTH-030-05-L-D-A-K improve signal integrity at high data rates?
The integrated ground plane between signal rows in QTH-030-05-L-D-A-K provides a continuous reference conductor that establishes controlled 50-ohm characteristic impedance for each signal contact. At data rates of 10 Gbps and higher, impedance discontinuities at connector transitions cause reflections that degrade eye diagram margins. The ground plane reduces crosstalk between adjacent differential pairs below -40 dB, supporting clean SerDes signal transmission in PCIe Gen 3, 10G Ethernet, and custom LVDS interfaces.
In which high-speed system architectures is QTH-030-05-L-D-A-K a preferred mezzanine connector?
QTH-030-05-L-D-A-K is preferred for FPGA daughter card interconnects, high-performance computing co-processor modules, and network switch line cards operating at 10 Gbps to 28 Gbps per lane. Its 0.50 mm pitch allows 60 positions — accommodating up to 15 differential pairs plus ground and power contacts — within a single connector. Networking OEMs also use it in 100G Ethernet optical transceiver cage interface boards where precise 50-ohm controlled impedance across the 60-pin mating interface is required.
How does QTH-030-05-L-D-A-K compare to 1.00 mm pitch high-speed connectors for compact PCB designs?
At 0.50 mm pitch, QTH-030-05-L-D-A-K delivers the same 60-position signal count as a 1.00 mm pitch connector that would span 30 mm, in a footprint of only 15 mm — a 50% board area reduction. The shorter stub length at 0.50 mm pitch also reduces parasitic inductance at each contact point by approximately 30% compared to 1.00 mm pitch alternatives, improving insertion loss by 1 dB to 2 dB at 10 GHz. This makes QTH-030-05-L-D-A-K the better choice for millimeter-wave and multi-Gbps interfaces.
