Frequently Asked Questions
What pitch and contact count does the SFM-149-T2-H-D-LC provide?
The SFM-149-T2-H-D-LC provides 98 total contacts arranged in 2 rows of 49 positions each, with a 1.27 mm (0.050 inch) pitch. This tight pitch enables circuit board designs that require high pin density within a footprint approximately 62 mm long, making it suitable for space-constrained mezzanine and module-to-backplane interfaces.
How does the SFM-149-T2-H-D-LC perform in high-speed signal integrity applications?
The SFM-149-T2-H-D-LC is engineered for high-reliability signal transmission with gold-plated contacts rated for low contact resistance. The 1.27 mm pitch and controlled-impedance socket design help minimize crosstalk between adjacent signal pairs, supporting data rates typical of modern FPGA and processor interconnects operating above 1 GHz with 50-ohm characteristic impedance.
What assembly process is compatible with the SFM-149-T2-H-D-LC surface mount termination?
The SFM-149-T2-H-D-LC uses surface mount technology (SMT) termination compatible with standard reflow soldering processes at peak temperatures up to 260°C per J-STD-020 guidelines. The T2 suffix indicates a specific lead style optimized for SMT pads, allowing automated pick-and-place assembly on standard 1.27 mm pitch PCB footprints without manual soldering.
When should an engineer choose SFM-149-T2-H-D-LC over a 2.54 mm pitch alternative?
Choosing SFM-149-T2-H-D-LC over a 2.54 mm pitch connector makes sense when board area is limited and a 98-contact interface must fit within roughly half the board space of a standard 2.54 mm pitch part. The 1.27 mm pitch reduces the connector footprint by approximately 75% in area, enabling denser PCB layouts in portable instruments, embedded computing modules, and satellite subsystems.
