Frequently Asked Questions
How does the T2 tail length of the SFM-123-T2-L-D-K-TR improve solder joint reliability?
The T2 extended tail protrudes further into the PCB pad, increasing solder contact area and mechanical anchoring. For a 46-position 0.050" pitch dual-row connector, this reduces susceptibility to joint cracking under thermal cycling between -40°C and +85°C operating conditions.
In what applications does a 46-pin dual-row 0.050" pitch socket like SFM-123-T2-L-D-K-TR offer advantages over wider-pitch alternatives?
A 46-position 0.050" pitch socket occupies roughly half the PCB footprint of equivalent 0.100" pitch parts, making it ideal for medical devices, compact robotics controllers, and FPGA daughter cards where board area is limited but 46 signal pins are needed.
What is the recommended mating connector for the SFM-123-T2-L-D-K-TR in a board-to-board stack?
SAMTEC SFM series sockets are designed to mate with corresponding SHF or TFM series headers at 0.050" pitch. For the 46-position dual-row SFM-123-T2-L-D-K-TR, a matching 46-position 0.050" dual-row header provides a fully mated board-to-board interconnect with reliable 46-pin signal continuity.
