Frequently Asked Questions
How many positions does the SFM-118-L2-H-D-LC have and what is its pitch?
The SFM-118-L2-H-D-LC is a 36-position dual-row socket strip, with 18 positions per row, at a 0.050" (1.27 mm) pitch. This combination provides a high pin-count interconnect in a small PCB footprint, making it ideal for signal-dense board-to-board applications in compact enclosures.
What does the 'H' designation mean in the SFM-118-L2-H-D-LC part number and when should engineers choose it?
The 'H' suffix in SFM-118-L2-H-D-LC designates a tall mating height variant, providing a larger board-to-board standoff distance compared to standard-profile versions. Engineers should select the H variant when through-hole components, capacitors, or other tall components on the mated board require additional vertical clearance, typically more than 3 mm above the PCB surface.
Which applications commonly use the SFM-118-L2-H-D-LC dual-row socket strip?
This 36-position, 1.27 mm pitch socket is used in industrial control modules, telecommunications line cards, defense electronics, and embedded processor boards where high pin count and reliable mating are required. Its surface mount design supports automated reflow assembly, and the gold-plated contacts maintain low contact resistance over thousands of mating cycles, ideal for environments with temperature swings from -55°C to +125°C.
What Samtec headers mate with the SFM-118-L2-H-D-LC connector?
The SFM-118-L2-H-D-LC mates with Samtec TSM and SFM series dual-row headers at 0.050" (1.27 mm) pitch. Compatible headers are available in surface mount and through-hole styles, giving designers flexibility in stack height and board orientation for 36-pin dual-row configurations.
