Key Features & Advantage

Automated SMT Assembly Ready: Designed specifically for surface-mount technology (SMT), featuring optional tape-and-reel packaging with pick-and-place caps to streamline high-speed automated factory assembly.
Versatile SV/SN Pad Layouts: Available in two distinct surface-mount lead structures—SV (with positioning alignment options) and SN configurations—to effortlessly adapt to different PCB trace routing and density needs.
Three Profile Heights Available: Offers adjustable plastic body heights (H=5.0mm, 7.1mm, 8.5mm) across the HFNSV/NSN 50, 71, and 85 series to perfectly tailor your vertical board-to-board stacking clearance.
High-Elasticity Phosphor Bronze Contacts: Built with high-grade Phosphor Bronze terminals, ensuring superior fatigue resistance, stable electrical paths, and reliable multi-mating lifetimes.
High-Temperature Thermoplastic Insulator: Utilizes advanced LCP or NL6T insulator materials rated at UL 94V-0, capable of safely enduring lead-free reflow soldering peak temperatures up to 260°C.
