Frequently Asked Questions
What is the position count and pitch of the SFM-148-L2-FM-D-LC, and what bus widths does it support?
The SFM-148-L2-FM-D-LC offers 96 positions in a dual-row layout at 0.050" (1.27 mm) pitch, accommodating bus widths up to 48 signal pairs or a 96-bit parallel bus. This density is well suited for wide memory bus interfaces, FPGA I/O headers, and high-channel-count analog signal routing in compact modules.
What does the FM flush-mount designation mean for the SFM-148-L2-FM-D-LC, and how does it help in stacked board assemblies?
FM indicates flush-mount height, meaning the SFM-148-L2-FM-D-LC sits extremely close to the PCB surface, typically under 2 mm above the board. In stacked board assemblies where board-to-board spacing may be as little as 4 mm, the flush-mount profile of the 96-pin connector ensures clearance for mating headers without exceeding the stack height budget.
How does the SFM-148-L2-FM-D-LC handle signal integrity for high-speed interfaces up to 500 MHz?
SAMTEC SFM series connectors like the SFM-148-L2-FM-D-LC are characterized for high-speed performance, typically maintaining insertion loss below 1 dB and return loss above 15 dB up to 500 MHz. The 0.050" pitch dual-row layout minimizes crosstalk between adjacent pins by keeping ground returns within 1.27 mm of each signal pin, supporting reliable differential pair routing across all 96 positions.
