Frequently Asked Questions
What does the -K suffix mean in SFM-138-02-F-D-A-K, and how does it benefit SMT assembly?
The -K suffix indicates a kinked lead option in the SFM-138-02-F-D-A-K, where the contact tails are bent to improve coplanarity before solder reflow. This reduces tombstoning and open-solder defects during automated SMT placement on 1.27 mm pitch pads, improving first-pass yield in high-volume production.
How does the 76-position count of SFM-138-02-F-D-A-K compare to other SFM series options for mezzanine designs?
Within SAMTEC's SFM series, 76 positions at 1.27 mm pitch occupies 48.26 mm of board length in a dual-row layout. Designers needing more pins can step up to 84-position or 98-position variants, while 76 pins covers most FPGA-to-carrier interfaces that require between 60 and 80 signal channels.
What is the per-pin current rating and contact plating of the SFM-138-02-F-D-A-K?
Each contact in the SFM-138-02-F-D-A-K is gold-plated and rated at 1A continuous current. With 76 pins in a dual-row 1.27 mm pitch layout, the connector supports mixed signal and low-power supply routing without exceeding contact thermal limits.
For a FPGA daughter card that mates 200 times over its service life, is SFM-138-02-F-D-A-K reliable enough?
SAMTEC high-reliability SFM series connectors including the SFM-138-02-F-D-A-K are rated for at least 100 mating cycles under standard conditions. For 200-cycle applications, specifying gold-plated contacts and avoiding lateral insertion forces ensures the 1A per pin rating and contact integrity are maintained throughout the product's service life.
