Key Features
- 96-position dual-row layout at 0.050" (1.27 mm) pitch enabling high-density fine-pitch board-to-board interconnects
- High-reliability gold-plated beryllium copper contacts rated at 1A per pin with low contact resistance for signal integrity
- Surface-mount termination compatible with standard SMT reflow processes for automated high-volume PCB assembly
Applications
The SFM-148-02-SM-D-A is designed for high-density mezzanine board interconnects in FPGA development systems, SoC carrier boards, and embedded computing modules where 96 signal connections at 1.27 mm pitch are needed in a minimal footprint. It is used in medical imaging systems, military avionics, and high-reliability industrial controllers where gold-plated contacts ensure long-term connection integrity under vibration and thermal cycling. The fine-pitch surface-mount profile suits compact rugged systems requiring dense I/O without through-hole assembly constraints.

Frequently Asked Questions
What pitch and pin count does SFM-148-02-SM-D-A offer for fine-pitch interconnect designs?
The SFM-148-02-SM-D-A provides 96 positions in a dual-row configuration with a 0.050" (1.27 mm) pin pitch. This fine pitch allows twice the contact density compared to standard 2.54 mm pitch connectors, making it ideal for high-density mezzanine and board stacking designs in compact embedded systems where PCB real estate is at a premium.
What is the current rating per pin for SFM-148-02-SM-D-A and how does that affect multi-rail power distribution?
Each contact in the SFM-148-02-SM-D-A is rated for 1A of continuous current. In a 96-position dual-row design, multiple adjacent pins can be ganged together to carry higher supply currents; for example, tying 5 pins per rail supports up to 5A per power net. This enables simultaneous distribution of multiple power rails (e.g., 1.8V, 3.3V, 5V) and high-speed signals in a single connector footprint.
How does the gold-plated contact finish of SFM-148-02-SM-D-A benefit high-cycle or high-reliability applications?
The gold-plated beryllium copper contacts in SFM-148-02-SM-D-A provide low and stable contact resistance over thousands of mating cycles, with gold plating typically rated for at least 100 insertion cycles without significant degradation. This makes it suitable for hot-swap test fixtures, removable mezzanine modules, and any application requiring consistent 1A signal or power performance across the operating temperature range.
