Frequently Asked Questions
What stack height and position count does the QRF8-026-05.0-L-D-A-GP provide for board-to-board designs?
The QRF8-026-05.0-L-D-A-GP offers a 5.0 mm stack height with 26 positions in a dual-row layout, enabling precise board-to-board spacing in compact telecom and computing assemblies where vertical clearance is tightly controlled.
How does Edge Rate (E.L.P.) technology in the QRF8-026-05.0-L-D-A-GP benefit high-speed differential signal designs?
Samtec's Edge Rate technology shapes the contact geometry to reduce impedance discontinuities at the connector interface. For differential signal pairs running at multi-gigabit rates, this lowers insertion loss and crosstalk compared to standard board stacking connectors, which matters in 10 GbE or PCIe interconnect designs.
Is the QRF8-026-05.0-L-D-A-GP suitable for applications requiring RoHS-compliant gold-plated contacts?
Yes. The -GP suffix indicates gold plating on the contacts, and Samtec lists this part as RoHS compliant with a Pb-free code. Gold plating provides low and stable contact resistance, typically under 20 milliohms, making it suitable for high-reliability telecom and industrial board stack-ups that must meet EU RoHS directives.
What PCB footprint area does the QRF8-026-05.0-L-D-A-GP body require on the host board?
The connector body measures approximately 1.116 inches in length and 0.246 inches in depth, with a 0.181 inch breadth. This compact footprint fits into tight board-to-board stack designs while providing 26 dual-row contacts across the connector length.
