What are the key features of SFM-106-L2-STL-D-A-K?
- 12-position dual-row stacking (STL) design at 0.050" (1.27 mm) pitch enables compact mezzanine interconnects with configurable board separation heights
- High-reliability SMT contacts rated from -55°C to +125°C maintain stable contact resistance below 20 milliohms across industrial environments
- Low pin-count format reduces PCB routing complexity while still supporting 6 differential pairs or 12 single-ended signals per connector
- Samtec SFM series compatibility ensures a precisely matched header-socket mating pair for reliable 12-pin board-to-board stacking
What is SFM-106-L2-STL-D-A-K used for?
The SFM-106-L2-STL-D-A-K is suited for compact daughter-board and mezzanine stacking applications where only 12 signals or power rails need to cross the board interface, such as small sensor modules, power-management daughter cards, and wireless radio add-on boards. Its stacking variant enables flexible inter-board spacing to accommodate components between the boards or provide airflow clearance. The SMT footprint allows reflow soldering alongside other surface-mount components in a single assembly pass.

Frequently Asked Questions
How many signal contacts does SFM-106-L2-STL-D-A-K provide, and what pitch separates them?
The SFM-106-L2-STL-D-A-K provides 12 contacts arranged in 2 rows of 6 positions each, with a 0.050-inch (1.27 mm) pitch between adjacent pins in each row. This compact footprint spans approximately 7.6 mm in length and supports up to 6 differential pairs (such as LVDS or MIPI) or 12 single-ended signal or power connections across the mezzanine interface.
What board separation heights are available for the STL (stacking) variant of SFM-106-L2-STL-D-A-K?
The STL stacking suffix indicates the connector mates with a corresponding header that sets the board-to-board separation distance. Samtec offers mating SFM or TSM series stacking headers in standard heights from approximately 3 mm to 20 mm, allowing designers to select the stack height needed to clear components placed between the two boards or to meet airflow and thermal management requirements.
For a compact RF sensor module, why is a 12-pin 0.050-inch pitch connector preferable to a 12-pin 0.100-inch pitch alternative?
At 0.050-inch (1.27 mm) pitch versus 0.100-inch (2.54 mm) pitch, the SFM-106-L2-STL-D-A-K occupies roughly half the PCB footprint length for the same 12-pin count—approximately 7.6 mm versus 15.2 mm. This size reduction is significant on RF sensor modules where board area is typically under 30 mm x 30 mm and every millimeter saved in connector length reduces parasitic capacitance and interference with adjacent antenna structures.
How does SFM-106-L2-STL-D-A-K perform in temperature-cycling environments typical of automotive or industrial designs?
The SFM-106-L2-STL-D-A-K is rated across -55°C to +125°C, which encompasses the AEC-Q200 temperature range for passive automotive components. The SMT gold-plated contacts maintain contact resistance below 20 milliohms after thermal cycling, and the connector housing material retains dimensional stability so the mating force and retention force remain within specification after repeated thermal excursions between -40°C and +105°C in a typical industrial duty cycle.
