What is QTE-020-04-C-D-A-K used for?
The QTE-020-04-C-D-A-K is used in high-speed board-to-board stacking assemblies for networking line cards, FPGA mezzanine modules, and storage controller daughterboards requiring 0.80 mm pitch signal density with integrated ground plane shielding. It suits high-frequency applications such as SerDes interfaces, DDR memory interfaces, and multi-gigabit serial links where maintaining 15 mΩ or lower contact resistance is critical to link margin. Telecom and datacom equipment designers use this Q Strip header to achieve tight pitch board stacking while preserving signal integrity across 4-row configurations.

Frequently Asked Questions
How does the integrated ground plane in the QTE-020-04-C-D-A-K improve signal integrity at high data rates?
The Q Strip ground plane structure in the QTE-020-04-C-D-A-K provides reference potential directly adjacent to signal contacts on the 0.80 mm pitch, reducing impedance discontinuities and crosstalk for differential pairs; this allows the connector to support multi-gigabit serial links at data rates up to several Gbps with lower signal skew compared to headers lacking an integrated ground reference.
What stack height and mating connector should be specified for the QTE-020-04-C-D-A-K in a 4-row dual-board assembly?
The QTE-020-04-C-D-A-K mates with SAMTEC QSE series receptacles; the 4-row (D) configuration on 0.80 mm pitch spans 20 positions providing 5 contacts per row, and the board body depth of 0.601 inch determines minimum board-to-board separation; designers select stack height by specifying the matching QSE receptacle height to achieve 2 mm to 12 mm board separation depending on the thermal and component clearance requirements of the assembly.
How does the 15 mΩ contact resistance specification of the QTE-020-04-C-D-A-K compare to industry standards for high-speed board connectors?
A 15 mΩ maximum contact resistance is well within the IPC and JEDEC guidelines for board-to-board connectors used in high-speed digital interfaces, where total path resistance budgets are typically under 50 mΩ per connection; the Sn over Ni contact finish on the QTE-020-04-C-D-A-K maintains this resistance through at least 100 mating cycles, ensuring consistent performance in both production assembly and field-serviceable module swaps.
