Key Features
- 0.100" (2.54 mm) pitch horizontal SMT socket compatible with standard 0.100" pin header connectors for broad interoperability
- 10 µin gold over 50 µin nickel contact finish provides reliable low-resistance mating, typically below 30 mΩ
- Horizontal surface-mount orientation keeps connector profile low, enabling compact enclosure designs
- Tiger Buy contact geometry ensures secure mating retention and consistent normal force across mating cycles
Applications
The SMH-103-02-L-S is used in low-profile board-to-board and board-to-cable interconnection scenarios in consumer electronics, industrial instruments, and embedded control systems. Its horizontal surface-mount configuration allows the mating connector to exit parallel to the PCB surface, ideal for panel-mounted boards with clearance constraints above the PCB. The 0.100" pitch standard ensures wide availability of mating pin headers and harness assemblies.

Frequently Asked Questions
What contact finish does the SMH-103-02-L-S use and how does it affect mating reliability?
The SMH-103-02-L-S uses 10 µin (0.25 µm) gold over 50 µin (1.27 µm) nickel on mating surfaces, with tin-nickel on termination tails. The gold finish prevents oxidation and maintains contact resistance below 30 mΩ through hundreds of mating cycles, making it suitable for signal-level connections in test fixtures and field-serviceable modules that are mated and demated regularly.
Why choose the horizontal SMT orientation of SMH-103-02-L-S over a vertical surface-mount socket?
The horizontal orientation routes the mating connector laterally relative to the PCB, which reduces the total height stack of the connected boards. In enclosures with less than 15 mm of vertical clearance above the PCB, a horizontal socket can enable a mating that a vertical socket at the same 0.100" pitch would not physically accommodate. This is particularly advantageous in slim panel instruments, handheld devices, and rack modules.
How does SMH-103-02-L-S perform compared to through-hole 0.100" socket strips in vibration-prone applications?
Surface-mount solder joints on SMH-103-02-L-S form a full perimeter fillet on the SMT pads, which distributes mechanical stress more uniformly than through-hole solder joints under vibration. In applications exposed to 5 G to 20 G vibration levels — such as industrial motor drives or vehicle electronics — properly reflowed SMT joints on the SMH-103-02-L-S pads typically outperform single-barrel through-hole connections due to the larger total solder joint area.
What PCB body dimensions should be reserved for SMH-103-02-L-S in a 6-position layout?
The SMH-103-02-L-S body measures approximately 0.32 inch (8.1 mm) in length, 0.095 inch (2.4 mm) in breadth, and 0.47 inch (11.9 mm) in depth (horizontal extension from the PCB edge). Board designers should reserve a keep-out zone at least 0.50 inch deep from the PCB edge in the mating direction and 0.35 inch wide to accommodate the connector body plus solder pad land patterns at 0.100" pitch.
