Frequently Asked Questions
What is the significance of the L2 mating height designation on SFM-108-L2-L-D-K-TR for board stacking?
The L2 designation on SFM-108-L2-L-D-K-TR specifies a defined mating height that controls the standoff distance between the two mated PCBs. This controlled height is critical in multi-board assemblies such as mezzanine card stacks, ensuring that the 16-pin dual-row 0.050" pitch connector maintains consistent mechanical and electrical contact while providing sufficient clearance for components on both boards.
For a 16-channel sensor interface board, why would SFM-108-L2-L-D-K-TR at 0.050" pitch be selected over a 0.100" pitch socket?
SFM-108-L2-L-D-K-TR at 0.050" pitch provides a 16-channel interface in approximately half the PCB length required by a 0.100" pitch equivalent. For compact sensor interface boards where all 16 channels must be routed within a tight form factor, the 0.050" pitch layout enables smaller overall board dimensions, reducing both PCB cost and enclosure size in applications such as medical monitoring devices and industrial IoT sensor modules.
Does the gold contact finish on SFM-108-L2-L-D-K-TR provide any advantage in low-voltage signal applications?
Yes, the gold-plated contacts on SFM-108-L2-L-D-K-TR significantly benefit low-voltage signal applications by maintaining very low and stable contact resistance, typically under 20 milliohms, across the 16-pin dual-row 0.050" interface. Gold resists oxidation and surface film formation that would increase resistance, which is critical in low-level analog signal and digital logic interfaces operating at 1.8 V to 3.3 V where even small contact resistance variations degrade signal integrity.
