Frequently Asked Questions
How many circuits does the SFM-145-02-FM-D-A-K provide, and what pitch does it use?
The SFM-145-02-FM-D-A-K provides 90 circuits arranged in a dual-row configuration on a 0.050-inch (1.27 mm) pitch. This fine-pitch, high-density layout accommodates 90 signal lines within a compact PCB footprint, making it suitable for applications where board space is critical and many connections must be made simultaneously.
Can the SFM-145-02-FM-D-A-K be used in FPGA mezzanine card designs requiring dense interconnects?
Yes, the SFM-145-02-FM-D-A-K is well-suited for FPGA mezzanine applications. Its 90-position, 1.27 mm pitch dual-row layout can carry high-speed signals at rates exceeding 1 Gbps per channel when paired with appropriate SAMTEC header strips. The SMT package integrates directly into standard reflow assembly workflows used on most mezzanine PCBs.
What is the physical profile difference between SFM-145-02-FM-D-A-K and a standard 2.54 mm pitch 90-position connector?
The SFM-145-02-FM-D-A-K uses a 1.27 mm (0.050-inch) pitch, which is half the spacing of a standard 2.54 mm pitch connector. This means the 90-position strip occupies roughly half the board length of a comparable 2.54 mm part, saving significant PCB real estate in compact embedded designs while maintaining 90 dual-row circuits.
Is the SFM-145-02-FM-D-A-K suitable for industrial environments with elevated temperatures?
The SFM-145-02-FM-D-A-K is built to SAMTEC's high-reliability standard with gold-plated contacts. SAMTEC SFM series connectors are typically rated for operating temperatures ranging from -55°C to +125°C, making them suitable for industrial automation, ruggedized computing, and telecom equipment where thermal robustness across 90 positions is required.
