Frequently Asked Questions
What contact count and pitch does SFM-121-L2-L-D-A-P-TR offer for mezzanine interconnect designs?
The SFM-121-L2-L-D-A-P-TR provides 42 positions in a dual-row (2x21) configuration at 0.050-inch (1.27 mm) pitch. This delivers 42 signal or power connections in a compact SMT footprint, making it effective for mezzanine board stacking in FPGA carrier cards and network interface modules requiring moderate-to-high pin counts.
How does SFM-121-L2-L-D-A-P-TR facilitate automated PCB assembly in production environments?
Supplied in tape-and-reel (TR) packaging, the SFM-121-L2-L-D-A-P-TR is compatible with standard pick-and-place machines and reflow soldering ovens operating at peak temperatures up to 260°C. This packaging format allows manufacturers to integrate 42-pin socket connectors into high-volume production lines for telecom and embedded computing equipment without manual placement.
When is SFM-121-L2-L-D-A-P-TR a better choice than a 0.100-inch pitch connector with the same pin count?
At 0.050-inch (1.27 mm) pitch, the SFM-121-L2-L-D-A-P-TR occupies roughly half the PCB area of an equivalent 0.100-inch (2.54 mm) pitch connector carrying the same 42 signals. This footprint advantage is critical in compact server blades, portable test instruments, and handheld industrial devices where board space is at a premium and 42 or more connections are needed.
