Frequently Asked Questions
What pitch and position count does the SFM-126-L2-ZZ-D-A-K-TR offer for board-to-board interconnects?
The SFM-126-L2-ZZ-D-A-K-TR provides 52 positions arranged in a dual-row configuration at a 0.050-inch (1.27 mm) pitch. This combination enables high-density PCB layouts in space-constrained designs while still delivering adequate pin count for mixed-signal or low-power distribution boards.
How does the SFM-126-L2-ZZ-D-A-K-TR differ from the SFM-129-series connectors?
The SFM-126-L2-ZZ-D-A-K-TR has 52 positions compared to 58 positions in the SFM-129 series, both sharing the same 0.050-inch (1.27 mm) pitch and dual-row SMT format. Designers choose the 52-position variant when routing constraints or signal count requirements fit within 26 pins per row, reducing board footprint by approximately 10%.
Can the SFM-126-L2-ZZ-D-A-K-TR be assembled using standard automated SMT equipment?
Yes, the SFM-126-L2-ZZ-D-A-K-TR comes in tape-and-reel (TR) packaging and uses surface-mount termination, making it fully compatible with automated pick-and-place equipment. Its 1.27 mm pitch footprint conforms to IPC-7351 SMT land pattern standards, supporting reflow solder profiles at peak temperatures up to 260°C.
What current per pin does the SFM-126-L2-ZZ-D-A-K-TR support in a mixed-signal design?
Each pin of the SFM-126-L2-ZZ-D-A-K-TR is rated at 1 A, totaling up to 52 A capacity across all 52 pins if used simultaneously at full load. In practical mixed-signal designs, pins are derated and voltage levels typically range from 1.8 V to 5 V, enabling both high-speed data and auxiliary power distribution on the same connector.
