Frequently Asked Questions
What is the contact pitch and total pin count of the SFM-148-L2-F-D-A-K?
The SFM-148-L2-F-D-A-K has a 0.050-inch (1.27 mm) contact pitch arranged in a dual-row configuration for a total of 96 pins across 2 rows of 48. This high-density layout allows 96 signal or power connections within a footprint of approximately 60 mm in length, making it suitable for compact board-to-board mezzanine designs.
What current rating do the SFM-148-L2-F-D-A-K contacts support per pin?
SAMTEC SFM series socket strips are typically rated at 1 A per contact at 30 V AC/DC, allowing designers to allocate multiple pins for higher-current power rails by paralleling contacts. Gold-plated contacts maintain low contact resistance below 20 milliohms, ensuring stable power delivery and signal integrity across the 96-position interface.
Which SAMTEC plug strip series mates with the SFM-148-L2-F-D-A-K?
The SFM-148-L2-F-D-A-K mates with SAMTEC's TSM and SFH series plug strips sharing the same 0.050-inch pitch and dual-row 48-per-row pattern. The mating connector stack height is approximately 4 mm when the L2 (2 mm above board) variant is used, providing consistent board separation for mezzanine card applications requiring clearance for components between layers.
Is the SFM-148-L2-F-D-A-K compatible with standard SMT reflow soldering at 260°C peak temperature?
Yes, the SFM-148-L2-F-D-A-K is designed for surface mount assembly and is compatible with standard SMT reflow profiles up to 260°C peak temperature, meeting IPC/JEDEC J-STD-020 requirements. The housing material retains dimensional stability during reflow, ensuring accurate placement of all 96 contacts within the solder pad land pattern on the PCB.
