Frequently Asked Questions
How does the 1.27 mm pitch of the SFM-117-L2-FM-D-A-K-TR compare to standard 2.54 mm pitch sockets for space savings?
The 1.27 mm (0.050") pitch reduces the connector footprint to approximately half the length of an equivalent 2.54 mm pitch socket for 34 positions. This allows designers to place the SFM-117-L2-FM-D-A-K-TR in compact FPGA daughter card designs and embedded modules where the available PCB area for interconnects is under 25 mm.
For a high-cycle mezzanine application requiring reliable insertion over 500 mating cycles, does the SFM-117-L2-FM-D-A-K-TR meet the requirement?
Yes. SAMTEC's SFM series high-reliability socket strips are rated for hundreds to over 1000 mating cycles with gold-plated contacts maintaining less than 20 mΩ contact resistance. For mezzanine modules in test fixtures or field-replaceable daughter cards subject to repeated plug-and-unplug cycles, the SFM-117-L2-FM-D-A-K-TR provides the durability needed across 34 positions.
Can the SFM-117-L2-FM-D-A-K-TR withstand lead-free reflow soldering temperatures during PCB assembly?
The SFM-117-L2-FM-D-A-K-TR is rated for surface mount reflow soldering at temperatures up to 260°C, fully compatible with lead-free (RoHS-compliant) assembly processes. Its SMT termination integrates cleanly into standard pick-and-place lines for the 34-position dual-row footprint without requiring manual through-hole soldering operations.
