Frequently Asked Questions
How many pins does the SFM-144-L2-FM-D-A-K-TR have and what pitch does it use?
The SFM-144-L2-FM-D-A-K-TR features 88 pins arranged in a dual row of 44 pins per row on a 1.27 mm (0.050-inch) pitch. This compact socket strip mounts to the PCB surface via a 2 mm solder tail, enabling reliable mezzanine board connections in space-constrained assemblies.
What temperature range does the SFM-144-L2-FM-D-A-K-TR support for aerospace-grade reliability?
SAMTEC's SFM series high-reliability socket strips are rated from -55°C to +125°C, meeting the demands of aerospace, defense, and harsh industrial environments. The 88-pin dual-row SMT construction withstands thermal cycling and vibration, maintaining consistent contact resistance across the full operating temperature range.
Which mezzanine module designs benefit from SFM-144-L2-FM-D-A-K-TR over a 2.54 mm pitch socket strip?
FPGA mezzanine cards, high-speed data acquisition modules, and compact single-board computers benefit from the SFM-144-L2-FM-D-A-K-TR because its 1.27 mm pitch packs 88 pins into half the footprint of an equivalent 2.54 mm pitch strip. This density advantage supports signal bandwidths above 500 MHz while reducing PCB area in multi-board embedded systems.
