Key Features
- 0.50 mm pitch 60-position dual-row terminal strip with integrated ground plane for superior signal integrity and controlled impedance at high data rates
- Q Strip high-speed design supports differential pair routing and reduces crosstalk between adjacent signal pairs in dense connector arrays
- Tape-and-reel (TR) packaging enables automated SMT assembly; K option provides keying to prevent incorrect mating with adjacent identical connectors
Applications
The QTH-030-07-L-D-A-K-TR is designed for high-speed PCB-to-PCB connections in FPGAs, high-performance computing modules, and multi-gigabit serial interface boards where signal integrity at 10 Gbps or beyond is critical. Its ground-plane construction and 0.50 mm pitch make it ideal for differential pairs used in SerDes, PCIe, and LVDS applications. The keying option prevents mismatched board stacking during automated and manual assembly of complex multi-board systems.

Frequently Asked Questions
What pitch and position count does the QTH-030-07-L-D-A-K-TR provide, and how does its ground plane benefit high-speed signals?
The connector offers 60 positions on a 0.50 mm pitch with an integrated ground plane between signal rows. The ground plane maintains a controlled characteristic impedance of approximately 50 Ω per differential pair, reducing inter-pair crosstalk at data rates above 5 Gbps.
Which high-speed serial protocols can the QTH-030-07-L-D-A-K-TR support given its electrical characteristics?
The Q Strip series with ground-plane construction is rated for multi-gigabit protocols including PCIe Gen 2/3, USB 3.x at 5 Gbps, and 10 GbE LVDS interfaces. The 0.50 mm pitch allows tightly controlled differential pair geometry needed to maintain eye diagrams compliant with SERDES specifications.
How does the keying (K) option on this connector prevent assembly errors in systems with multiple identical connector sites?
The K keying feature adds a mechanical polarization element that physically blocks mating with an unkeyed or differently keyed counterpart. In systems with 2 or more QTH connector sites on the same PCB, this eliminates board reversal errors that could damage 60 high-speed signal traces and associated ICs.
What stack height does the 07 designation specify for the QTH-030-07-L-D-A-K-TR?
The 07 suffix indicates a 7 mm mated stack height between the two PCBs, providing 7 mm of air gap for inter-board components such as decoupling capacitors up to 5 mm tall or low-profile EMI filters, while keeping the overall board stack compact.
