What are the key features of SFM-133-L2-SM-D-LC?
- 66 positions in dual-row 0.050" (1.27 mm) pitch for ultra-high-density surface mount interconnects
- High-reliability socket strip design with gold-plated contacts for low insertion loss and long cycle life
- Surface mount termination in a low-profile package compatible with standard SMT reflow assembly
- 1 A per contact rating supports signal and low-power distribution in compact multi-board systems
What is SFM-133-L2-SM-D-LC used for?
The SFM-133-L2-SM-D-LC is used in high-density board-to-board and module-to-carrier interconnect applications in aerospace, defense electronics, and advanced computing where fine-pitch 0.050 inch connectors are required. Its 66-position dual-row socket configuration enables compact routing of wide data buses or mixed signal-and-power buses within a minimal PCB footprint. The high-reliability construction makes it suitable for designs requiring extended operating temperature ranges and resistance to vibration or shock.

Frequently Asked Questions
What pitch and contact count does the SFM-133-L2-SM-D-LC offer compared to standard 0.100 inch socket strips?
The SFM-133-L2-SM-D-LC uses a 0.050 inch (1.27 mm) pitch with 66 total contacts in a dual-row layout (33 positions per row), which is half the pitch of standard 0.100 inch connectors. This finer pitch allows the same contact count in roughly half the board length, making it ideal for space-constrained high-density interconnect designs in aerospace or advanced computing applications.
How much current can each contact in the SFM-133-L2-SM-D-LC carry?
Each contact in the SFM-133-L2-SM-D-LC is rated at 1 A, consistent with SAMTEC's SFM high-reliability series specifications for 0.050 inch pitch socket strips. This 1 A per pin rating supports signal distribution and light-power bus lines such as 3.3 V or 5 V supply rails, while ensuring reliable thermal performance across all 66 positions during continuous operation.
Is the SFM-133-L2-SM-D-LC compatible with automated SMT assembly, and what solder profile does it require?
Yes, the SFM-133-L2-SM-D-LC is a surface mount component designed for standard SMT pick-and-place assembly. It is compatible with lead-free reflow solder profiles peaking at up to 260 °C in accordance with IPC/JEDEC J-STD-020 guidelines, allowing direct integration into modern RoHS-compliant production lines without requiring hand soldering or special thermal management of the connector body.
In which high-reliability application segments is the SFM-133-L2-SM-D-LC typically specified over lower-cost alternatives?
The SFM-133-L2-SM-D-LC is specified over lower-cost socket strips in aerospace avionics, defense subsystems, and high-end test-and-measurement equipment where operating temperatures span -55 °C to +125 °C and the connector must survive thousands of mating cycles without measurable contact resistance increase. Its gold-plated contacts and SAMTEC high-reliability qualification make it a direct fit for programs requiring stringent MTBF targets.
