What are the key features of SFM-147-02-STL-D-LC?
- 94-position dual-row configuration at 0.050" (1.27 mm) pitch supports very high signal count in a compact connector footprint
- Straddle-mount (STL) termination style provides mechanical stability on the PCB edge, resisting vibration and shock
- Low-crosstalk (LC) contact design minimizes signal interference across adjacent contacts in high-speed data applications
- High-reliability gold-plated contacts rated for -55°C to +125°C operating temperature and multiple mating cycles
What is SFM-147-02-STL-D-LC used for?
The SFM-147-02-STL-D-LC is designed for high-density mezzanine card and FPGA daughter board applications where 94 signals must be routed across boards in a minimal footprint. The straddle-mount SMT termination provides added mechanical stability for applications subject to vibration, such as industrial control systems and defense electronics. It is commonly used in embedded computing modules, telecom line cards, and test and measurement platforms requiring robust, high-density board-to-board interconnects.

Frequently Asked Questions
What is the total pin count and physical layout of SFM-147-02-STL-D-LC?
The SFM-147-02-STL-D-LC provides 94 total positions in a dual-row layout with 47 contacts per row at 0.050 inch (1.27 mm) pitch. This configuration spans approximately 61 mm of board length, making it one of the larger SFM socket strips for applications demanding very high signal count in a single connector interface.
How does the straddle-mount (STL) termination of SFM-147-02-STL-D-LC improve connector retention compared to standard SMT?
The straddle-mount style wraps solder tails around the PCB edge, gripping both the top and bottom surfaces and providing superior pull resistance compared to standard surface-mount pads. This increases the connector's resistance to shear forces during insertion and mating cycles, which is critical in portable and field-deployed equipment subject to 5g or greater mechanical shock.
In which high-density signal routing scenarios is SFM-147-02-STL-D-LC preferred over multi-connector alternatives?
When a design requires 94 or more signals between two boards, using a single SFM-147-02-STL-D-LC eliminates the alignment complexity and additional board space of multiple smaller connectors. At 1.27 mm pitch, the 94-position connector occupies roughly the same board area as a pair of 50-position 1.27 mm connectors but with a single mating interface, reducing assembly steps and potential misalignment errors.
What is the significance of the LC (low-crosstalk) designation in the SFM-147-02-STL-D-LC part number?
The LC suffix in SAMTEC SFM connectors indicates optimized contact geometry and spacing designed to reduce capacitive and inductive coupling between adjacent signal pins. This is important in applications where multiple high-speed differential pairs or single-ended signals at 100 MHz and above are routed through the connector, helping meet signal integrity budgets in fast data acquisition or communications systems.
