Key Features
- 82-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch for ultra-high-density board-to-board mating
- High-reliability (H) contact system engineered for extended mating life exceeding 500 cycles with consistent normal force
- Precision machined contacts with gold plating provide low contact resistance below 15 mΩ and corrosion resistance
- Surface-mount termination supports automated reflow soldering up to 260°C for seamless high-volume PCB assembly
Applications
The SFM-141-02-H-D-A-K high-reliability socket strip is engineered for mission-critical applications in defense electronics, aerospace payload boards, and high-availability server platforms requiring more than 80 signal connections with extended service life. Its 1.27 mm pitch dual-row layout fits FPGA mezzanine cards and multi-channel data converter boards where 82 simultaneous signal paths are needed in a compact SMT footprint. The high-reliability contact rating ensures consistent performance in environments with thermal cycling from -55°C to +125°C and moderate vibration levels.

Frequently Asked Questions
What does the H designation in SFM-141-02-H-D-A-K indicate about the connector's performance rating?
The H designation indicates a high-reliability contact configuration, which specifies a mating life typically rated at 500 or more insertion and withdrawal cycles versus the standard 200-cycle rating. High-reliability contacts use tighter manufacturing tolerances and heavier gold plating, often 50 µin or greater on the mating surface, to maintain contact resistance below 15 mΩ throughout the connector's service life in demanding aerospace, defense, or industrial environments.
How does the 82-position count of SFM-141-02-H-D-A-K support high-density FPGA or signal processing board designs?
With 82 positions at 0.050" (1.27 mm) pitch, the SFM-141-02-H-D-A-K can carry up to 41 differential pairs or 82 single-ended signals across a dual-row footprint spanning approximately 52 mm in length. This pin count is sufficient to route a full LVDS or LVPECL bus from a large FPGA device to a mezzanine digitizer card without additional connector banks, simplifying PCB layout and reducing the number of discrete connectors needed on the mother board.
What temperature range and environmental conditions is the SFM-141-02-H-D-A-K rated for?
The SFM-141-02-H-D-A-K is rated for operation across a temperature range of -55°C to +125°C, covering the full industrial and military thermal envelope. The SMT housing material is selected to withstand reflow soldering at up to 260°C peak temperature per IPC/JEDEC J-STD-020. Gold-plated contacts resist oxidation in humidity environments up to 95% relative humidity, making this socket strip suitable for outdoor industrial enclosures and sealed avionics chassis with MIL-STD-810 vibration requirements.
When would a designer choose SFM-141-02-H-D-A-K over a lower-cost standard-reliability alternative?
A designer selects the SFM-141-02-H-D-A-K when the mating module or mezzanine card will be inserted and removed frequently, such as field-replaceable units with 200+ lifetime cycles, or when the system must meet reliability standards such as MIL-SPEC, DO-160, or IEC 61508 SIL 2 and above. The higher per-unit cost of 50 µin gold plating and tighter contact tolerances is justified in applications where connector failure causes safety risk or unacceptable downtime, compared to a 30 µin standard contact rated only for 100 cycles.
