Key Features
- 100-position dual-row (50x2) surface mount socket at 0.050" (1.27 mm) pitch provides maximum signal channel density for high-pin-count board-to-board interfaces
- High-reliability gold-plated contacts ensure low contact resistance across extended mating cycle life in demanding interconnect applications
- Surface mount termination enables single-pass reflow assembly of all 100 contacts on standard SMT production lines without secondary soldering
Applications
The SFM-150-L2-H-D-A-K is designed for high-channel-count board-to-board interfaces in FPGA evaluation platforms, high-performance computing modules, and data acquisition systems where 100 signal channels must pass through a compact 0.050" pitch footprint. Its dual-row 50x2 surface mount configuration allows dense PCB routing in server blades, network processing cards, and signal processing boards where channel count and PCB real estate are both constrained. The connector is also widely used in modular radar, software-defined radio, and imaging systems requiring wide parallel data buses.

Frequently Asked Questions
How many signal positions does SFM-150-L2-H-D-A-K provide, and how does the 0.050" pitch compare to 0.100" pitch alternatives for a 100-pin interface?
SFM-150-L2-H-D-A-K provides 100 positions in a dual-row (50x2) layout at a 0.050" (1.27 mm) pitch. At 0.050" pitch, the connector body for 100 positions is approximately 50% shorter than an equivalent 0.100" (2.54 mm) pitch connector, allowing the same 100 signal channels to occupy half the board length and enabling significantly denser PCB component placement in space-constrained designs.
For which high-pin-count applications is SFM-150-L2-H-D-A-K the appropriate choice over a lower-position SFM series variant?
SFM-150-L2-H-D-A-K is the right choice when the interface requires exactly 100 signal channels, such as a wide 64-bit data bus plus address and control lines on an FPGA daughter card, or a 100-pin parallel camera or sensor interface. When fewer than 100 channels are needed, lower-position variants such as SFM-129 (58 pins) or SFM-122 (44 pins) reduce connector length and cost, but SFM-150 is necessary when the full 100-channel count is required.
What assembly process is SFM-150-L2-H-D-A-K compatible with, and how does surface mount termination simplify production for 100-pin connectors?
SFM-150-L2-H-D-A-K uses surface mount termination compatible with standard SMT reflow soldering at peak temperatures of 245°C to 260°C. All 100 positions are soldered simultaneously in a single reflow pass alongside other SMT components, eliminating the manual or wave soldering steps required for through-hole 100-pin alternatives and reducing assembly time proportionally compared to mixed-technology board builds.
How does the gold-plated contact finish of SFM-150-L2-H-D-A-K support signal integrity across 100 channels in a high-speed parallel bus?
Gold-plated contacts maintain contact resistance typically below 20 milliohms per pin across thousands of mating cycles, which is critical for a 100-channel parallel bus where cumulative resistance variation across all pins would otherwise degrade signal margins. Gold also resists oxidation and fretting corrosion, keeping all 100 channels at consistent impedance and minimizing inter-channel skew in high-speed data interfaces operating at tens to hundreds of MHz.
