What are the key features of SFM-133-02-FM-D?
- 66-pin dual-row female SMT socket strip on 1.27 mm (0.050 inch) pitch for high-density board-to-board signal and power routing
- 0.20 inch mated stack height enabling compact multi-board assemblies in embedded computing and FPGA module designs
- High-reliability surface mount termination compatible with automated pick-and-place and reflow soldering production processes
What is SFM-133-02-FM-D used for?
The SFM-133-02-FM-D is used in embedded processor modules, FPGA daughterboards, and industrial backplane systems requiring 66 signals at 1.27 mm pitch in a compact SMT socket format. Its dual-row layout enables wide parallel bus interfaces and combined power-and-signal routing between stacked PCBs at a 0.20 inch mated height. The high-reliability design suits test-and-measurement instrumentation, medical device motherboards, and military electronics where signal integrity across all 66 channels is essential.

Frequently Asked Questions
How many pins does SFM-133-02-FM-D provide and how are they arranged in the connector?
The SFM-133-02-FM-D is a 66-pin dual-row female SMT socket strip with 33 positions per row on a 1.27 mm (0.050 inch) pitch. This high contact density enables wide parallel bus interfaces, combined address and data lines, or mixed signal and power distribution between two PCBs in a compact stacked board assembly.
What board-to-board stack height and signal bandwidth does SFM-133-02-FM-D support in embedded designs?
The SFM-133-02-FM-D achieves a 0.20 inch board-to-board mated stack height, making it ideal for FPGA expansion modules, processor daughtercards, and mezzanine sockets where PCB clearance is limited. Its 66 pins of female SMT contacts support high-speed signals up to 3 GHz, accommodating differential pairs and parallel bus structures in performance-critical embedded systems.
How does SFM-133-02-FM-D compare to SFM-120-02-FM-D and SFM-144-02-FM-D when selecting the right bus connector?
SFM-133-02-FM-D offers 66 pins for interfaces requiring 33 positions per row, falling between SFM-120-02-FM-D with 40 pins and SFM-144-02-FM-D with 88 pins on the same 1.27 mm pitch. Designers choose the 66-pin variant when a 32-bit data bus plus address and control signals totaling 66 channels can be consolidated into a single SMT connector, avoiding partial row usage or the complexity of two separate connectors.
