QFS-078-01-SL-D-EM2

The QFS-078-01-SL-D-EM2 from Samtec Inc. is a high-performance Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) engineered for demanding board-to-board applications. This connector delivers exceptional signal integrity and power distribution capabilities, making it ideal for 5G base stations and high-speed computing systems. With its advanced contact technology and robust construction, it ensures reliable performance in harsh operating environments.Featuring a Receptacle, Center Strip Contacts configuration, this solution provides optimal mating stability while minimizing insertion loss. When compared to conventional designs, the patented contact geometry reduces crosstalk by up to 30%.Available in 156 contact arrangements, the connector supports flexible power delivery configurations. System designers can choose between signal-dominant or power-optimized layouts based on application requirements.The ultra-fine 0.025" (0.64mm) spacing enables high-density PCB layouts without compromising signal integrity. This precision spacing is particularly beneficial for miniaturized RF modules and compact embedded systems.With 2 rows configuration, the connector achieves balanced impedance characteristics across all channels. The symmetrical layout minimizes skew variation for high-speed differential pairs.Designed for Board Edge, Straddle Mount installation, this connector simplifies assembly processes while maintaining mechanical robustness. The mounting system has been validated for automated pick-and-place operations.The inclusion of Ground Bus (Plane) enhances both reliability and manufacturability. These engineered features address common challenges in vibration-prone applications while improving ESD protection.Utilizing Gold plating technology, the contacts maintain low contact resistance over 10,000 mating cycles. This finish selection provides optimal performance in humid environments.
