Frequently Asked Questions
What is the total contact count and pitch of the SFM-137-T2-SM-D-A-P, and what connector footprint does this create?
The SFM-137-T2-SM-D-A-P provides 148 total contacts arranged in 74 dual-row positions at 1.27 mm (0.050 inch) pitch. This results in a connector footprint approximately 47 mm in length, suitable for compact mezzanine board sockets and high-density FPGA expansion interfaces where board space is limited.
What does the T2 contact designation mean for the SFM-137-T2-SM-D-A-P in vibration-prone environments?
The T2 contact style in the SFM-137-T2-SM-D-A-P refers to an enhanced contact geometry that increases the normal force applied to mating pins, improving mechanical retention under vibration. This makes the connector suitable for industrial automation, aerospace, and transportation electronics where PCB assemblies may be exposed to continuous vibration levels above 5 g.
How does the 0.050 inch pitch of the SFM-137-T2-SM-D-A-P benefit high-speed signal integrity compared to 0.100 inch pitch connectors?
At 1.27 mm (0.050 inch) pitch, the SFM-137-T2-SM-D-A-P achieves twice the contact density of 2.54 mm pitch connectors, reducing interconnect length and parasitic capacitance. This supports higher signal speeds and is compatible with differential pair routing at frequencies up to several gigahertz, making it preferred for high-speed data buses in FPGA and communications designs.
Is the SFM-137-T2-SM-D-A-P available in tape-and-reel packaging for automated SMT production?
The SFM-137-T2-SM-D-A-P with the -P suffix indicates tray or tape packaging options suitable for automated SMT pick-and-place assembly. The surface mount termination is compatible with standard lead-free reflow profiles peaking at 260°C, supporting RoHS-compliant high-volume manufacturing of industrial and communications PCB assemblies.
