Key Features
- 20-position dual-row board stacking header with 0.80 mm pitch optimized for high-speed signal integrity with integrated ground planes
- Gold-flash over nickel contact finish on mating surface with tin/nickel barrier on termination for corrosion resistance and reliable electrical connection
- Phosphor bronze contacts designed for repeated mating cycles in board-to-board stacking configurations
Applications
The QTE-020-04-F-D-A-K is designed for high-speed board-to-board stacking applications in telecommunications equipment, networking hardware, and high-frequency embedded computing platforms where signal integrity is paramount. The integrated ground plane structure of the Q Strip series reduces crosstalk and electromagnetic interference at data rates above 1 Gbps. Its compact 0.80 mm pitch enables dense interconnect solutions in space-constrained mezzanine card assemblies.

Frequently Asked Questions
What pitch and position count does the QTE-020-04-F-D-A-K offer for board stacking?
The QTE-020-04-F-D-A-K provides 20 positions arranged in a dual-row configuration on a 0.80 mm pitch, enabling a high-density board-to-board stacking interface in a compact footprint. Gold-flash over nickel contacts on the mating surface maintain reliable electrical performance through hundreds of mating cycles, with typical contact resistance below 20 milliohms.
How does the integrated ground plane of the Q Strip series improve signal performance at high data rates?
The Q Strip ground plane header interleaves ground contacts between signal pins, reducing cross-talk and maintaining controlled impedance at data rates exceeding 1 Gbps per channel. This architecture allows the QTE-020-04-F-D-A-K to support differential pairs and single-ended signals simultaneously across a 0.80 mm pitch footprint, making it suitable for PCIe, USB 3.0, and similar high-speed interfaces in stacked board designs.
When should a designer choose QTE-020-04-F-D-A-K over a standard 2.00 mm pitch stacking connector?
When board area is constrained and signal density must be maximized, the 0.80 mm pitch of the QTE-020-04-F-D-A-K achieves over 6x higher pin density per unit length compared to 2.00 mm pitch alternatives, allowing 20 dual-row positions in under 9 mm of board length. This trade-off is most advantageous in compact mezzanine modules, FPGA expansion cards, and telecommunication blades where every square millimeter of PCB area has a significant cost impact.
