Applications
The SFM-110-L2-L-D-LC-TR is used in embedded system designs, test-and-measurement daughterboards, and small FPGA evaluation modules where 20 dual-row signals must be routed at 1.27 mm pitch in a minimal board area of 0.655 x 0.185 inches. Its tape-and-reel format and board-lock retention feature make it ideal for automated, high-reliability SMT assembly in industrial and communications equipment.

Frequently Asked Questions
What contact finish does SFM-110-L2-L-D-LC-TR use, and how does it affect connector reliability over mating cycles?
The SFM-110-L2-L-D-LC-TR uses gold (10 microinches) over nickel (50 microinches) on the mating contacts, providing low and stable contact resistance below 20 milliohms across hundreds of mating cycles. Gold plating prevents oxidation and fretting corrosion, which is critical for signal integrity in high-frequency applications operating at 1.27 mm pitch in embedded computing and instrumentation boards.
How does the split board-lock feature on SFM-110-L2-L-D-LC-TR assist PCB assembly?
The split board-lock feature consists of retention posts that insert into PCB holes and snap to hold the connector in position before and during soldering. This mechanical retention prevents connector movement and tilt during reflow oven passes at up to 260 °C, ensuring all 20 SMT pads align correctly and reducing solder joint defects in high-volume automated assembly of dual-row 0.050 inch pitch socket strips.
What are the body dimensions of SFM-110-L2-L-D-LC-TR, and how much PCB real estate does it require?
The body of the SFM-110-L2-L-D-LC-TR measures 0.655 inch long by 0.185 inch deep by 0.145 inch wide, occupying approximately 16.6 mm x 4.7 mm of PCB surface area. This compact footprint, combined with the 20-pin dual-row 1.27 mm pitch layout, allows designers to fit the connector in tight spaces on daughter cards, sensor modules, or FPGA expansion boards with minimal routing overhead.
When is SFM-110-L2-L-D-LC-TR preferred over a through-hole 20-pin dual-row connector for mezzanine applications?
SFM-110-L2-L-D-LC-TR is preferred over through-hole alternatives when the design requires surface-mount assembly to minimize PCB thickness, reduce drill count, and support automated tape-and-reel placement. At 20 contacts in a 10 x 2 configuration at 1.27 mm pitch, it occupies approximately 16.6 mm board length versus a standard through-hole 2.54 mm pitch connector of the same pin count, roughly halving the footprint while maintaining signal integrity for low-to-moderate frequency signals.
