Frequently Asked Questions
What pitch and position count does the SFM-102-02-SM-D-K-TR socket strip use?
The SFM-102-02-SM-D-K-TR is a dual-row socket strip with 4 positions total (2 per row) at a 0.050 inch (1.27 mm) pitch. This fine pitch format is designed for high-density PCB layouts where space is limited, enabling compact board-to-board or daughter card connections in 2x2 dual-row configurations.
For which SMT assembly process is the SFM-102-02-SM-D-K-TR packaging optimized?
The TR (tape-and-reel) packaging of the SFM-102-02-SM-D-K-TR is optimized for automated pick-and-place SMT assembly. Standard reel formats hold hundreds to thousands of units, supporting high-volume reflow soldering processes with lead-free solder profiles up to 260°C peak, meeting IPC/JEDEC J-STD-020 MSL requirements.
How does the SFM-102-02-SM-D-K-TR compare to through-hole socket strips at the same pitch?
The SFM-102-02-SM-D-K-TR surface-mount version occupies less board height than through-hole equivalents, with an SMT footprint that allows single-sided PCB assembly. At 0.050 inch (1.27 mm) pitch dual-row, the SMT socket delivers comparable electrical performance — typically under 50 mΩ contact resistance — while enabling finer PCB trace routing around the connector pad area.
Which compact embedded applications benefit most from the dual-row 0.050 inch pitch format of the SFM-102-02-SM-D-K-TR?
Compact embedded computing modules, FPGA daughter boards, and high-speed data acquisition cards benefit from the SFM-102-02-SM-D-K-TR's 0.050 inch (1.27 mm) pitch dual-row 4-position layout. The small footprint supports board stacking with minimal standoff height, making it suitable for multi-board assemblies in UAV avionics, medical devices, and portable test instruments requiring up to 1 A per contact current rating.
