What are the key features of SFM-102-T2-STL-D-A-K-TR?
- High-reliability dual-row socket strip at 0.050" (1.27 mm) pitch supports dense 4-position SMT signal connections with robust contact retention
- Stacked solder tail (STL) design provides increased solder joint strength for mechanical stability on high-vibration SMT boards
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly for high-volume SMT production lines
What is SFM-102-T2-STL-D-A-K-TR used for?
The SFM-102-T2-STL-D-A-K-TR high-reliability socket strip is used in compact embedded computing modules, aerospace sub-systems, and industrial control cards where a 4-position dual-row 0.050" pitch SMT receptacle must mate repeatedly with header pins under vibration conditions. Its stacked solder tail configuration improves mechanical retention compared to standard single-tail designs, making it preferred in applications subject to shock loads up to several g. Engineers designing small-footprint mezzanine cards and high-reliability daughtercards specify this socket for its combination of compact 1.27 mm pitch and enhanced solder joint robustness.

Frequently Asked Questions
What solder tail design does the SFM-102-T2-STL-D-A-K-TR use, and how does it improve mechanical reliability?
The SFM-102-T2-STL-D-A-K-TR uses a stacked solder tail (STL) design that provides two solder attachment points per contact instead of one. This doubles the solder joint area for each of the 4 positions in the dual-row 0.050" (1.27 mm) pitch socket, significantly improving pull-out strength and resistance to mechanical shock and vibration.
For which compact SMT board applications is the 4-position 0.050" pitch SFM-102-T2-STL-D-A-K-TR best suited?
This 4-position dual-row socket at 0.050" (1.27 mm) pitch fits mezzanine board expansions, compact industrial sensor modules, aerospace avionics cards, and embedded computing daughterboards where PCB real estate is limited and connector pitch must stay at 1.27 mm or less. The high-reliability contact design supports repeated mating cycles in field-serviceable equipment.
How does the SFM-102-T2-STL-D-A-K-TR tape-and-reel packaging support high-volume manufacturing?
The TR suffix designates tape-and-reel packaging compatible with standard SMT pick-and-place machines. Reels of this 4-position 0.050" pitch dual-row socket can feed automated placement equipment at production rates typical of consumer and industrial PCB lines, reducing manual handling errors compared to bulk or tray-packaged connectors.
