Applications
The SFM-144-T2-STL-D is designed for high-density daughter card connections, FPGA mezzanine interfaces, and module-to-carrier board assemblies where space is at a premium. Its 0.050-inch pitch and 88-position dual-row configuration supports dense signal routing in test and measurement instruments, embedded computing systems, and telecommunications equipment. The SMT footprint and high contact count make it ideal for automated assembly environments requiring repeatable, reliable interconnects.

Frequently Asked Questions
How does the 0.050-inch pitch of SFM-144-T2-STL-D benefit high-density PCB designs compared to standard 0.100-inch pitch connectors?
The 0.050-inch (1.27 mm) pitch on the SFM-144-T2-STL-D packs 88 positions into roughly half the board footprint of a comparable 0.100-inch pitch connector, enabling 44 additional signal pins in the same PCB area, which is critical for FPGA mezzanine and compact module designs.
What current and voltage ratings apply to the SFM-144-T2-STL-D for mixed-signal PCB interconnect planning?
Each contact in the SFM-144-T2-STL-D is rated at 1 A continuous current and 150 V working voltage, making the 88-position dual-row strip suitable for digital signal lines and low-power supply rails but not for high-current power distribution exceeding 1 A per pin.
Which mating Samtec pin header series is compatible with SFM-144-T2-STL-D for a stacking mezzanine assembly?
The SFM-144-T2-STL-D mates with Samtec's TSM and TMS series 0.050-inch pitch pin headers; the dual-row 88-position format requires a matching 44-per-row male header with gold-plated pins to maintain the specified 1 A per contact and 150 V isolation performance.
When is SFM-144-T2-STL-D preferred over a press-fit or through-hole socket for test and measurement board designs?
The SMT termination of the SFM-144-T2-STL-D eliminates the need for drilled through-holes in the PCB, reducing fabrication cost and enabling routing on inner layers beneath the 88-position, 0.050-inch pitch footprint—an advantage in multi-layer boards used in precision test and measurement instruments.
