Frequently Asked Questions
How does the 1.27mm pitch of SFM-123-L2-L-D-A-K compare to standard 2.54mm pitch connectors in board density?
The SFM-123-L2-L-D-A-K uses a 1.27mm (0.050 inch) pitch, which is half the spacing of standard 2.54mm pitch connectors. This allows designers to fit 46 positions in approximately half the PCB footprint, doubling connection density for space-constrained embedded systems, FPGA boards, and compact communication modules.
What makes SFM-123-L2-L-D-A-K suitable for high-reliability applications?
SFM-123-L2-L-D-A-K is classified as a high-reliability socket strip, featuring gold-plated contacts that maintain low contact resistance (typically below 20 milliohms) across all 46 positions over thousands of mating cycles. This makes it appropriate for aerospace, medical instrumentation, and industrial control applications where connector failure is not acceptable.
Can SFM-123-L2-L-D-A-K be used in automated SMT manufacturing processes?
Yes, SFM-123-L2-L-D-A-K is a surface mount component compatible with standard SMT pick-and-place and reflow soldering processes. Its surface mount pads support lead-free reflow at up to 260°C, enabling efficient high-volume PCB assembly with standard solder pastes and reflow profiles used across the electronics manufacturing industry.
Which signal or interface types can SFM-123-L2-L-D-A-K support in a dual-row configuration?
SFM-123-L2-L-D-A-K's 46-position dual-row design supports a wide range of signal types including LVDS, SPI, I2C, parallel data buses up to 16-bit wide, power, and ground rails simultaneously. Its 1.27mm pitch layout is commonly used in FPGA mezzanine card interfaces, memory module sockets, and multi-channel analog-to-digital converter boards.
