Frequently Asked Questions
What pitch and row configuration does the SFM-118-T2-SM-D use, and how does that affect PCB layout density?
The SFM-118-T2-SM-D uses a 0.050-inch (1.27 mm) pitch in a dual-row configuration across 36 positions, resulting in a body length of approximately 1.055 inches. This fine pitch allows placement in very tight PCB areas, making it suitable for high-density mezzanine and board-to-board connector designs where board space is critical.
Which industrial or embedded computing designs benefit most from the SFM-118-T2-SM-D's contact finish combination?
The gold-plated mating contacts paired with tin-over-nickel termination finish provide low contact resistance (typically under 20 milliohms) and excellent corrosion resistance. Industrial control boards, embedded computing modules, and test equipment operating in environments with moderate humidity or temperature cycling up to 85°C benefit from this finish combination, reducing connector failures over thousands of mating cycles.
How does the SFM-118-T2-SM-D compare to through-hole socket strips when selecting for automated SMT assembly lines?
As a surface mount device, the SFM-118-T2-SM-D is compatible with standard SMT pick-and-place equipment and reflow soldering processes, eliminating the need for wave soldering or manual insertion required by through-hole alternatives. Its body dimensions of 1.055 inches length by 0.185 inch depth fit standard SMT land patterns, reducing assembly cycle time and improving placement accuracy to within ±0.1 mm on modern assembly lines.
